fix(frontend): resolve UI rate limiting on Docker overview (#859)

Previously, each DockerContainerRow component made 2 API calls on mount:
- AIAPI.getSettings() for AI enabled status
- DockerMetadataAPI.getMetadata() for annotations

With 100+ containers, this resulted in 200+ API calls firing simultaneously,
exceeding the 500 requests/minute rate limit and causing 429 errors.

Fix:
- Lift AI settings check to DockerUnifiedTable parent component (1 call)
- Use pre-fetched dockerMetadata prop for annotations (already batch-fetched)
- Pass aiEnabled and initialNotes as props to child rows

This reduces API calls from O(n*2) to O(1) when loading the Docker overview.

Fixes #859
