feat(mcp): add serply-search server catalog entry (#3085)

Adds an opt-in HTTP entry for Serply's hosted MCP endpoint to mcp-configs/mcp-servers.json, following the parallel-search and browser-use shape: https URL, X-Api-Key header placeholder, nothing enabled by default. Independent review confirmed valid JSON, catalog-tier policy per docs/MCP-CONNECTOR-POLICY.md, and that the endpoint itself answers 401 asking for X-Api-Key, so the placeholder header is warranted. CI 44/44 at the head.
