fix(trmnl): drop the timestamp overlay, the dashboard has a clock card

The dashboard now carries a type: clock card, which the browser draws at capture time — so the time in the image is already the time the screenshot was taken, and the renderer's overlay would print it twice. Supersedes the overlay added a commit ago, which was itself replacing a Home Assistant template sensor that fired a state-changed event and wrote a recorder row every minute. The card does the same job with no entity, no event and no row. Pairs with homeassistant#221. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

claude-botandClaude Opus 5	e2fa885fa3	fix(trmnl): burn the render time into the image, not into an entity Sets the schedule's `timestamp` option, which the renderer already supports and which I had written out as false without asking what it did — the same mistake as leaving `lang` null. The freshness stamp was a Home Assistant template sensor formatting now(). That fired a state-changed event, woke every listener and wrote a recorder row EVERY MINUTE, forever, so the panel could draw a line of text. Pairs with homeassistant#221, which deletes it. Baking it into the PNG is also more correct, not just cheaper. The panel is poll-only and shows the last image indefinitely if the renderer dies, so the stamp exists to prove the image is fresh. A time read from an entity proves Home Assistant was alive when the shot was taken; a time drawn by the renderer proves the RENDER happened, which is the failure actually being guarded against.

claude-botandClaude Opus 5	507e86cb83	fix(trmnl): let Reloader restart the renderer on config and secret changes ci/woodpecker/pr/ci-scripts-test Pipeline was successful Details ci/woodpecker/pr/ci-manifests-test Pipeline was successful Details ci/woodpecker/pr/pr-review Pipeline was successful Details The renderer's init container writes /data/schedules.json ONCE, at pod start, and nothing re-reads either source afterwards. So a ConfigMap or Secret change lands in git, updates the object, and the running renderer keeps the old values indefinitely. The app re-reads schedules.json every 60 seconds, which makes it look self-updating. It is not — it re-reads the FILE, and only the init container writes the file. This was hit three times in practice, each needing `kubectl delete pod` by hand: * switching the theme to Graphite E-ink Light — the pod kept rendering with a theme name that no longer existed * setting the schedule's lang field to "de" * every re-mint of the BYOS tokens, which is the Secret half The theme case is the instructive one: nothing errored. HA silently served the default theme for a name that did not resolve, so the panel just looked wrong, and I was about to debug the design. Annotates both sources. Named per-resource rather than the blanket reloader.stakater.com/auto: "true", matching terminus.yaml and mosquitto-deployment.yaml. Terminus got this annotation earlier; the renderer did not, despite having the same init-container pattern and hitting the same failure in the same session.
