🔄 refactor: MCP Server Init and Stale Cache Handling (#10984)

Browse source 
* 🔧 refactor: Update MCP connection handling to improve performance and testing

* refactor: Replace getAll() with getLoaded() in MCP.js to prevent unnecessary connection creation for user-context servers.
* test: Adjust MCP.spec.js to mock getLoaded() instead of getAll() for consistency with the new implementation.
* feat: Enhance MCPServersInitializer to reset initialization flag for better handling of process restarts and stale data.
* test: Add integration tests to verify re-initialization behavior and ensure stale data is cleared when necessary.

* 🔧 refactor: Enhance cached endpoints config handling for GPT plugins

* refactor: Update MCPServersInitializer tests to use new server management methods

* refactor: Replace direct Redis server manipulation with registry.addServer and registry.getServerConfig for better abstraction and consistency.
* test: Adjust integration tests to verify server initialization and stale data handling using the updated methods.

* 🔧 refactor: Increase retry limits and delay for MCP server creation

* Updated MAX_CREATE_RETRIES from 3 to 5 to allow for more attempts during server creation.
* Increased RETRY_BASE_DELAY_MS from 10 to 25 milliseconds to provide a longer wait time between retries, improving stability in server initialization.

* refactor: Update MCPServersInitializer tests to utilize new registry methods

* refactor: Replace direct access to sharedAppServers with registry.getServerConfig for improved abstraction.
* test: Adjust tests to verify server initialization and stale data handling using the updated registry methods, ensuring consistency and clarity in the test structure.
