🗃️ refactor: Simplify MCP Server Config to Two-Repository Pattern (#10705)

Browse source 
* refactor(mcp): simplify registry to two-repository architecture with explicit storage

* Chore: address AI Review comments

* Simplify MCP config cache architecture and remove legacy code:
Follow-up cleanup to commit d2bfdd033 which refactored MCP registry to two-repository architecture. This removes leftover legacy abstractions that were no longer used.
 What changed:
  - Simplified ServerConfigsCacheFactory.create() from 3 params to 2 (namespace, leaderOnly)
  - Removed unused scope: 'Shared' | 'Private' parameter (only 'Shared' was ever used)
  - Removed dead set() and getNamespace() methods from cache classes
  - Updated JSDoc to reflect two-repository architecture (Cache + DB) instead of old three-tier system
  - Fixed stale mocks and comments referencing removed sharedAppServers, sharedUserServers, privateServersCache

  Files changed:
  - ServerConfigsCacheFactory.ts - Simplified factory signature
  - ServerConfigsCacheRedis.ts - Removed scope, renamed owner→namespace
  - ServerConfigsCacheInMemory.ts - Removed unused methods
  - MCPServersRegistry.ts - Updated JSDoc, simplified factory call
  - RegistryStatusCache.ts - Removed stale JSDoc reference
  - MCPManager.test.ts - Fixed legacy mock
  - ServerConfigsCacheFactory.test.ts - Updated test assertions

* fix: Update error message in MCPServersRegistry for clarity
