fix: pin MCP sidecar versions for stability

Browse Source 
- Pin kubernetes-mcp to v0.0.57 (Jan 27, 2025) with token exchange and field selector support
- Pin flux-mcp to v0.41.1 (already pinned)
- Pin homeassistant-mcp to v6.7.1 (Feb 20, 2026) - latest stable release
- Update documentation with version details
- Bump chart version to 0.1.19

This ensures reproducible deployments and prevents unexpected breaking changes
from floating tags (latest/stable).

**Note:**
- Kubernetes and Flux sidecars require `clusterAccess` != `none` to be deployed (they need RBAC permissions)

## MCP Sidecars
- **Kubernetes MCP** (port 8080): Only deployed when enabled AND `clusterAccess` != `none`
- **Flux MCP** (port 8081): Only deployed when enabled AND `clusterAccess` != `none`
- **Home Assistant MCP** (port 8087): Disabled by default, requires secrets:
- **Kubernetes MCP** (v0.0.57, port 8080): Only deployed when enabled AND `clusterAccess` != `none`
- **Flux MCP** (v0.41.1, port 8081): Only deployed when enabled AND `clusterAccess` != `none`
- **Home Assistant MCP** (v6.7.1, port 8087): Disabled by default, requires secrets:
- `homeassistant-url`: Base URL like `http://homeassistant.local:8123`
- `homeassistant-token`: Long-lived access token
- **Playwright MCP**: External service, not a sidecar
- Configure via `mcpSidecars.<name>.enabled` in values
- **Version Strategy**: All MCP images use pinned versions for stability (no `latest` tags)
## Common Gotchas
- `baseimage-gui` creates user dynamically — don't hardcode usernames in scripts, use numeric UID/GID
