Expose HTTP origins in MCP server status (#47159)

## What changed

Add nullable `httpOrigin` to `McpServerStatus`, derived from the effective configured endpoint for both configured and plugin-provided servers. Return only the HTTP(S) origin, excluding credentials, path, query, and fragment; return `null` for stdio transports, invalid URLs, and non-HTTP(S) schemes. Update the generated protocol schemas and TypeScript and Python types.

## Testing

Extend status integration tests to cover configured and plugin-provided HTTP servers, verify that endpoint paths and query parameters are omitted, and assert `null` for a stdio server. Update protocol tests to check null serialization and compatibility with older inventory responses.
