📡 refactor: MCP Runtime Config Sync with Redis Distributed Locking (#10352)

Browse source 
* 🔄 Refactoring: MCP Runtime Configuration Reload
 - PrivateServerConfigs own cache classes (inMemory and Redis).
 - Connections staleness detection by comparing (connection.createdAt and config.LastUpdatedAt)
 - ConnectionsRepo access Registry instead of in memory config dict and renew stale connections
 - MCPManager: adjusted init of ConnectionsRepo (app level)
 - UserConnectionManager: renew stale connections
 - skipped test, to test "should only clear keys in its own namespace"
 - MCPPrivateServerLoader: new component to manage logic of loading / editing private servers on runtime
 - PrivateServersLoadStatusCache to track private server cache status
 - New unit and integration tests.
Misc:
 - add es lint rule to enforce line between class methods

* Fix cluster mode batch update and delete workarround. Fixed unit tests for cluster mode.

* Fix Keyv redis clear cache namespace  awareness issue + Integration tests fixes

* chore: address copilot comments

* Fixing rebase issue: removed the mcp config fallback in single getServerConfig method:
- to not to interfere with the logic of the right Tier (APP/USER/Private)
- If userId is null, the getServerConfig should not return configs that are a SharedUser tier and not APP tier

* chore: add dev-staging branch to workflow triggers for backend, cache integration, and ESLint checks

/**
* Cache for tracking MCP Servers Registry metadata and status across distributed instances.
* Cache for tracking MCP Servers Registry global metadata and status across distributed instances.
* Uses Redis-backed storage to coordinate state between leader and follower nodes.
* Currently, tracks initialization status to ensure only the leader performs initialization
* while followers wait for completion. Designed to be extended with additional registry
* metadata as needed (e.g., last update timestamps, version info, health status).
* Tracks global initialization status for the registry.
*
* Note: Per-user private server loading status is tracked separately in PrivateServersLoadStatusCache
* to enable TTL synchronization and distributed locking.
*
* Designed to be extended with additional global registry metadata as needed
* (e.g., last update timestamps, version info, health status).
* This cache is only meant to be used internally by registry management components.
