🧩 refactor: Decouple MCP Config from Startup Config (#10689)

* Decouple mcp config from start up config

* Chore: Work on AI Review and Copilot Comments

- setRawConfig is not needed since the private raw config is not needed any more
- !!serversLoading bug fixed
- added unit tests for route /api/mcp/servers
- copilot comments addressed

* chore: remove comments

* chore: rename data-provider dir for MCP

* chore: reorganize mcp specific query hooks

* fix: consolidate imports for MCP server manager

* chore: add dev-staging branch to frontend review workflow triggers

* feat: add GitHub Actions workflow for building and pushing Docker images to GitHub Container Registry and Docker Hub
