🔒 feat: Add MCP server domain restrictions for remote transports (#11013)
* 🔒 feat: Add MCP server domain restrictions for remote transports

* 🔒 feat: Implement comprehensive MCP error handling and domain validation

- Added `handleMCPError` function to centralize error responses for domain restrictions and inspection failures.
- Introduced custom error classes: `MCPDomainNotAllowedError` and `MCPInspectionFailedError` for better error management.
- Updated MCP server controllers to utilize the new error handling mechanism.
- Enhanced domain validation logic in `createMCPTools` and `createMCPTool` functions to prevent operations on disallowed domains.
- Added tests for runtime domain validation scenarios to ensure correct behavior.

* chore: import order

* 🔒 feat: Enhance domain validation in MCP tools with user role-based restrictions

- Integrated `getAppConfig` to fetch allowed domains based on user roles in `createMCPTools` and `createMCPTool` functions.
- Removed the deprecated `getAllowedDomains` method from `MCPServersRegistry`.
- Updated tests to verify domain restrictions are applied correctly based on user roles.
- Ensured that domain validation logic is consistent and efficient across tool creation processes.

* 🔒 test: Refactor MCP tests to utilize configurable app settings

- Introduced a mock for `getAppConfig` to enhance test flexibility.
- Removed redundant mock definition to streamline test setup.
- Ensured tests are aligned with the latest domain validation logic.
