Operator: Change default proxy mode from SSE to streamable-http (#2521)

* Change default proxy mode from SSE to streamable-http

Update the Kubernetes Operator to default to streamable-http proxy mode
instead of the deprecated SSE transport for stdio-based MCP servers.

Changes:
- Update CRD default annotation from sse to streamable-http
- Update controller default logic to use streamable-http
- Update unit tests to expect streamable-http as default
- Regenerate CRD manifests and documentation
- Bump operator-crds chart version from 0.0.52 to 0.0.53
- Bump operator chart version from 0.3.7 to 0.3.8
- Add explicit proxyMode: sse to existing stdio e2e tests
- Add new stdio-streamable-http e2e test scenarios for both
  single-tenancy and multi-tenancy

The streamable-http transport is the recommended approach per the MCP
specification. Users can still explicitly set proxyMode: sse if needed.

Fixes #2211
