🏹 feat: Concurrent MCP Initialization Support (#8677)

* ✨ feat: Enhance MCP Connection Status Management

- Introduced new functions to retrieve and manage connection status for multiple MCP servers, including OAuth flow checks and server-specific status retrieval.
- Refactored the MCP connection status endpoints to support both all servers and individual server queries.
- Replaced the old server initialization hook with a new `useMCPServerManager` hook for improved state management and handling of multiple OAuth flows.
- Updated the MCPPanel component to utilize the new context provider for better state handling and UI updates.
- Fixed a number of UI bugs when initializing servers

* 🗣️ i18n: Remove unused strings from translation.json

* refactor: move helper functions out of the route module into mcp service file

* ci: add tests for newly added functions in mcp service file

* fix: memoize setMCPValues to avoid render loop
