Persist LocalAI state and match the live deployment

- Keep agents, KB collections, users and runtime settings
  (LOCALAI_DATA_PATH, LOCALAI_CONFIG_DIR) and backends
  (LOCALAI_BACKENDS_PATH) on the models PVC. The chart's /data,
  /configuration and /backends are ephemeral, so every pod restart wiped
  the agent team and the llama.cpp backend.
- Default the agent pool to ornith-1.5-9b-q8 with
  granite-embedding-107m-multilingual embeddings.
- Make the image tag a variable, defaulting to the CUDA 13 image that runs.
- Patch hostNetwork and the LOCALAI_P2P_TOKEN secretKeyRef (Secret
  localai/localai-p2p) onto the Deployment after Helm. Both were set by
  hand, and applying the role would otherwise revert them.
