fix(llama-embed): raise the memory limit to match its own context and batch

#739 raised the context from 2048 to 4096 and the micro-batch from an effective
512 to 1024, both to match how Paperless chunks documents. It left memory at
2Gi/4Gi, which was sized for the smaller values.

The pod ran fine interactively and was OOMKilled (exit 137) partway through the
first sustained run, around 300 documents into an embedding pass. Nothing in the
server log marked it — the process was killed outright, so the last line is a
half-finished task and the reason is only visible in the container's
lastState.terminated.

This would have surfaced when Paperless first indexed the archive, i.e. on the
first real use rather than under test.

The weights are only ~600 MiB. What sets the footprint is four slots at 4096
context with a 1024-token micro-batch, plus Vulkan allocating the iGPU working
set from system RAM where it counts against this cgroup — the same effect that
put llama-server at 32Gi for 19 GiB of weights.

-# paperless-data: CephFS → RBD
-
-## Why
-
-`paperless-data` is `ReadWriteMany` on `ceph-filesystem`, but **only the paperless
-Deployment mounts it**. Verified 2026-08-20:
-
-```
-$ pods mounting paperless-data
-paperless-68cb8b8744-7hjb8      <- one, and only one
-
-paperless-data     ReadWriteMany  ceph-filesystem
-paperless-media    ReadWriteMany  ceph-filesystem   <- genuinely shared (ftp-scanner)
-paperless-consume  ReadWriteMany  ceph-filesystem   <- genuinely shared (ftp-scanner)
-```
-
-Its contents are single-writer state — the 50 MB Whoosh index,
-`classification_model.pickle`, `celerybeat-schedule.db`, `log/`,
-`migration_lock`, `protonmail.pem`. 75 files. Nothing else reads or writes them.
-
-It is on CephFS by default, not by requirement.
-
-## What it costs
-
-Every access goes through the MDS. Measured with **zero CI pipelines running**:
-
-```
-paperless-data client   request_load_avg 22   (all other sessions 0-1)
-MDS over 180s           4,052 client requests  = 22.5/s
-                        2,718 journal events   = 15/s
-                            2 dir commits      <- almost none: not file writes
-```
-
-So it is cap/inode churn from repeated access, not data being written. That is
-most of the constant **7-8 GB/day** written to `cephfs-metadata`, and since that
-pool is `size: 3`, roughly **21-24 GB/day** reaches the drives.
-
-`cephfs-metadata` deliberately stays at size 3. Losing it destroys the entire
-filesystem rather than the objects on one OSD, and the 275 GiB in `cephfs-data0`
-depends on it. Cutting the writes at source is correct; cutting the replication
-is not.
-
-## Sequence
-
-Staged deliberately: the PVC lands first and empty, so merging it changes
-nothing. The copy and the repoint are separate.
-
-### Phase 1 — provision (this PR)
-
-`paperless-data-block` (RWO, `ceph-block`, 10Gi) is created and mounted by
-nothing. Inert.
-
-Verify: `kubectl -n paperless get pvc paperless-data-block` → Bound.
-
-### Phase 2 — copy
-
-The Whoosh index must come across intact. Paperless *can* rebuild it
-(`document_index reindex`), but that reprocesses every document, so copying is
-both faster and less disruptive.
-
-1. Scale paperless to 0. The source must be quiescent — `celerybeat-schedule.db`
-   and the Whoosh index are both live-written, and copying them under an active
-   writer gives a torn read.
-2. Run a one-off pod that mounts BOTH PVCs and copies:
-   ```
-   cp -a /src/. /dst/
-   ```
-   The RWO target pins the pod to one node; the RWX source will follow.
-3. Verify file count and index size match:
-   ```
-   find /src -type f | wc -l   ==   find /dst -type f | wc -l
-   du -sh /src/index           ==   du -sh /dst/index
-   ```
-
-### Phase 3 — repoint
-
-Change the Deployment's `data` volume to `claimName: paperless-data-block`,
-merge, let it roll.
-
-Verify afterwards:
-- paperless starts, search returns results (proves the Whoosh index survived)
-- `ceph tell mds.cephfs-b session ls` no longer shows a busy `paperless-data`
-  client
-- `rate(ceph_pool_wr_bytes{pool_id="3"})` drops from its 7-8 GB/day baseline
-
-**Do not delete `paperless-data` until search has been confirmed working.** It is
-the rollback, and it is `prune: disabled` so Flux will not remove it.
-
-## Expected effect
-
-~7-8 GB/day off `cephfs-metadata`, so ~21-24 GB/day off the drives once
-replication is counted. Against ~432 GB/day cluster-wide that is roughly 5% —
-worth doing, but it is a correctness fix (a single-writer volume does not belong
-on a shared filesystem) more than a large win.
-
-It also removes 22 req/sec of MDS load, which benefits the workloads that
-genuinely need CephFS — Woodpecker CI workspaces share the same MDS.
