🔏 fix: MCP Server URL Schema Validation (#12204)
* fix: MCP server configuration validation and schema

- Added tests to reject URLs containing environment variable references for SSE, streamable-http, and websocket types in the MCP routes.
- Introduced a new schema in the data provider to ensure user input URLs do not resolve environment variables, enhancing security against potential leaks.
- Updated existing MCP server user input schema to utilize the new validation logic, ensuring consistent handling of user-supplied URLs across the application.

* fix: MCP URL validation to reject env variable references

- Updated tests to ensure that URLs for SSE, streamable-http, and websocket types containing environment variable patterns are rejected, improving security against potential leaks.
- Refactored the MCP server user input schema to enforce stricter validation rules, preventing the resolution of environment variables in user-supplied URLs.
- Introduced new test cases for various URL types to validate the rejection logic, ensuring consistent handling across the application.

* test: Enhance MCPServerUserInputSchema tests for environment variable handling

- Introduced new test cases to validate the prevention of environment variable exfiltration through user input URLs in the MCPServerUserInputSchema.
- Updated existing tests to confirm that URLs containing environment variable patterns are correctly resolved or rejected, improving security against potential leaks.
- Refactored test structure to better organize environment variable handling scenarios, ensuring comprehensive coverage of edge cases.
