docs(zigbee2mqtt): record the WS90 ZCL reporting configuration

The Wetterstation now carries a non-default reporting configuration: min
interval 5s on all ten reportable attributes, and tighter reportable-change
deadbands on temperature, humidity and pressure. None of it is expressible
in configuration.yaml - Zigbee2MQTT has no settings-schema field for
reporting configuration - so it lives only on the device and in Z2M's
database.db. This documents it and how to restore it.

min was 10s against an 8.8s transmit interval. Since min is a hold-off, every
change-triggered report was held past a transmit cycle and landed on the
next, so attributes reported at best every 17.6s and drifted out of phase.
The published stream showed no 8.8s periodicity at all. At min 5 each
attribute reports on its own transmit and the stream carries one publish per
cycle, measured at a mean gap of 8.69s. Publish volume fell from ~631/h to
~445/h because each publish is now a whole cycle rather than a fragment.

The deadbands come from the shared modernExtend helpers, which the WS90
definition composes without overrides. They are anti-chatter values sized for
battery-powered indoor sensors. Temperature was 1.00 C, giving a staircase
that moved about twice an hour; it is now 0.1 C, matching the resolution the
device actually reports. Pressure was 5 kPa - 50 hPa, which real barometric
pressure never traverses, so it only ever updated on the hourly heartbeat
that pressure_trend and weather_condition derive from. Note the same library
configures the identical ZCL attribute with a 5 hPa deadband in its older
reporting.ts helper, so the two code paths disagree by 10x.

Anything that makes Z2M re-run configure on the device reverts all of it, and
a fresh PVC will not have it. The restore commands are written out literally
rather than generated by a shell helper, because the nested quoting through
`kubectl exec -- sh -c` is where this goes wrong; each was executed and
verified as written, including the read-back, and re-applying is a no-op.

No behaviour change from this commit itself - the device was reconfigured at
runtime, this only records it.

+# WS90 Zigbee reporting configuration
+
+Records the ZCL attribute-reporting configuration applied to the Wetterstation
+(Ecowitt WS90 powered by Shelly, IEEE `0xc02cedfffe958f40`) and how to restore
+it, because **this configuration lives on the device and in Z2M's
+`database.db`, not in git**. Zigbee2MQTT has no settings-schema field for
+reporting configuration, so there is nothing declarative to reconcile — Flux
+cannot restore it and a fresh PVC will not have it.
+
+## Applied configuration
+
+Endpoint 1, all intervals in seconds. `change` is in the attribute's raw ZCL
+units; the physical deadband is `change ÷ scale`.
+
+| attribute | cluster | min | max | change | deadband | converter default |
+| --- | --- | --- | --- | --- | --- | --- |
+| temperature | `msTemperatureMeasurement` (1026) | 5 | 3600 | 10 | 0.1 °C | 10 / 3600 / 100 |
+| humidity | `msRelativeHumidity` (1029) | 5 | 3600 | 50 | 0.5 % | 10 / 3600 / 100 |
+| pressure | `msPressureMeasurement` (1027) | 5 | 3600 | 1 | 1 hPa | 10 / 3600 / 50 |
+| illuminance | `msIlluminanceMeasurement` (1024) | 5 | 3600 | 5 | 5 lx | 10 / 3600 / 5 |
+| windSpeed | `shellyWS90Wind` (0xfc01/0) | 5 | 3600 | 1 | — | 10 / 3600 / 1 |
+| windDirection | `shellyWS90Wind` (0xfc01/4) | 5 | 3600 | 1 | — | 10 / 3600 / 1 |
+| gustSpeed | `shellyWS90Wind` (0xfc01/7) | 5 | 3600 | 1 | — | 10 / 3600 / 1 |
+| uvIndex | `shellyWS90UV` (0xfc02/0) | 5 | 3600 | 1 | — | 10 / 3600 / 1 |
+| rainStatus | `shellyWS90Rain` (0xfc03/0) | 5 | 3600 | 1 | — | 10 / 3600 / 1 |
+| precipitation | `shellyWS90Rain` (0xfc03/1) | 5 | 3600 | 1 | — | 10 / 3600 / 1 |
+
+`genPowerCfg.batteryVoltage` (cluster 1, attribute 33) is deliberately left at
+its hourly default.
+
+The three `shellyWS90*` clusters are manufacturer-specific and require
+`"options": {"manufacturerCode": 5264}` on every reconfiguration request.
+
+## Why min is 5 and not 10
+
+The station transmits every 8.8 s. `min` is a hold-off: a change-triggered
+report is held until at least `min` seconds after the previous one. With
+`min: 10` every report was therefore held past a transmit cycle and landed on
+the next, so attributes reported at best every 17.6 s and drifted out of phase
+with each other — the published stream showed no 8.8 s periodicity at all,
+just a smear across 2–8 s.
+
+At `min: 5` each attribute reports on its own transmit. The MQTT stream then
+carries one publish per transmit cycle, measured at a mean gap of 8.69 s.
+Total publish volume *fell* (~631/h to ~445/h) because each publish now
+carries a whole cycle instead of a fragment of one.
+
+Any value below 8.8 s achieves this. 5 leaves margin without approaching the
+cycle time.
+
+## Why the deadbands differ from the converter defaults
+
+The defaults come from the shared `modernExtend` helpers in
+zigbee-herdsman-converters (`m.temperature()`, `m.pressure()`, `m.humidity()`,
+`m.illuminance()`), which the WS90 definition in `shelly.ts` composes without
+overrides. They are anti-chatter values sized for battery-powered indoor
+sensors, where report volume costs coin-cell life and mesh airtime. This
+station is mains-and-solar and exists to resolve small changes, so the
+trade-off runs the other way.
+
+Each value above is matched to the resolution the device actually reports:
+temperature and pressure arrive in 0.1-unit steps, humidity in whole percent.
+
+Pressure is worth calling out. The converter default of `change: 50` with
+`scale: 10` is a 5 kPa (50 hPa) deadband, which real barometric pressure never
+traverses — so pressure only ever updated on the hourly `max` heartbeat, and
+`pressure_trend` and `weather_condition` were derived from that. The same
+library's older `reporting.ts` helper configures the identical ZCL attribute
+with `change: 5`, a 5 hPa deadband, so the two code paths disagree by 10× and
+the modernExtend value is the outlier.
+
+## When this is lost
+
+Anything that makes Z2M re-run `configure` on the device overwrites all of it
+with the converter defaults:
+
+- re-pairing or re-joining the device
+- an explicit `zigbee2mqtt/bridge/request/device/configure`
+- a converter update that changes the definition and triggers reconfiguration
+
+It also will not exist on a fresh PVC. Re-apply with the commands below.
+
+## Re-applying
+
+Published from the `discovery-guard` sidecar, which already holds the
+`zigbee2mqtt` broker credential (ACL `readwrite zigbee2mqtt/#`, which covers
+`bridge/request/#`) so no credential has to leave the cluster:
+
+Ten separate requests, one per attribute — written out literally rather than
+generated by a shell helper, because the nested quoting through `kubectl exec
+-- sh -c` is where this goes wrong. Each line below is in the exact form that
+was executed and verified.

+```
+
+These are idempotent — re-sending a request that matches the current
+configuration is a no-op on the device.
+
+The device must be awake and reachable; each request performs a real
+`ConfigureReporting` exchange and fails if it is not.
+
+## Verifying
+
+Read back what the device actually accepted — Z2M records the negotiated
+result, so this reflects the device, not the request:
+
+```sh
+kubectl exec -n home-assistant "$POD" -c zigbee2mqtt -- \
+  grep 0xc02cedfffe958f40 /app/data/database.db |
+  jq -r '.endpoints | to_entries[] | .value.configuredReportings[]?
+         | "cluster=\(.cluster) attr=\(.attrId) min=\(.minRepIntval) max=\(.maxRepIntval) change=\(.repChange)"'
+```
+
+All ten rows above should read `min=5 max=3600`. On the wire, the publish
+cadence on `zigbee2mqtt/Wetterstation` should sit at ~8.7 s and temperature
+should move in 0.1 °C steps; 1 °C steps mean the defaults are back.
+
+## Making it durable upstream
+
+The lasting fix is for the WS90 definition to pass explicit `reporting`
+overrides rather than inherit indoor-sensor defaults, which would fix every
+WS90 rather than this one. `m.temperature()` and the other helpers already
+accept a `reporting` argument. The pressure divergence between
+`modernExtend.ts` and `reporting.ts` is a separate upstream bug worth
+reporting on its own.
