✨ feat: Add MCP Reinitialization to MCPPanel (#8418)

* ✨ feat: Add MCP Reinitialization to MCPPanel

- Refactored tool caching to include user-specific tools in various service files.
- Refactored MCPManager class for clarity
- Added a new endpoint for reinitializing MCP servers, allowing for dynamic updates of server configurations.
- Enhanced the MCPPanel component to support server reinitialization with user feedback.

* 🔃 refactor: Simplify Plugin Deduplication and Clear Cache Post-MCP Initialization

- Replaced manual deduplication of tools with the dedicated `filterUniquePlugins` function for improved readability.
- Added back cache clearing for tools after MCP initialization to ensure fresh data is used.
- Removed unused exports from `PluginController.js` to clean up the codebase.
