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

* 🔄 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
