Remove Deprecated Port from MCPRemoteProxy Types

[ChrisJBurns]

Description

Remove the deprecated Port field from MCPRemoteProxySpec and simplify its helper method.

Implementation Notes

File: cmd/thv-operator/api/v1alpha1/mcpremoteproxy_types.go

Field to remove: Port (line ~48) — proxyPort is the canonical field.

Note: MCPRemoteProxy is being deprecated by RFC-0057 in favour of MCPRemoteEndpoint. This cleanup is minimal — just removing the deprecated field alias to keep the API clean for the remaining v1alpha2 lifetime.

Post-implementation: Run task gen.

Acceptance Criteria

• Port field removed from MCPRemoteProxySpec
• Helper method simplified
• task gen succeeds

This was fully addressed in PR #4467 (merged 2026-03-31, commit 029ecbd), which removed six deprecated CRD fields including MCPRemoteProxy.spec.port.

All three acceptance criteria are met:

• Port field removed from MCPRemoteProxySpec -- the Port int32 field and its json:"port,omitempty" tag were deleted.
• Helper method simplified -- GetProxyPort() was reduced from a multi-branch fallback to a straightforward two-line method that checks ProxyPort and falls back to 8080.
• task gen succeeds -- the PR passed CI, which includes code generation.

Thanks for filing this!
