🛡️ fix: Secure MCP/Actions OAuth Flows, Resolve Race Condition & Tool Cache Cleanup (#11756)
* 🔧 fix: Update OAuth error message for clarity

- Changed the default error message in the OAuth error route from 'Unknown error' to 'Unknown OAuth error' to provide clearer context during authentication failures.

* 🔒 feat: Enhance OAuth flow with CSRF protection and session management

- Implemented CSRF protection for OAuth flows by introducing `generateOAuthCsrfToken`, `setOAuthCsrfCookie`, and `validateOAuthCsrf` functions.
- Added session management for OAuth with `setOAuthSession` and `validateOAuthSession` middleware.
- Updated routes to bind CSRF tokens for MCP and action OAuth flows, ensuring secure authentication.
- Enhanced tests to validate CSRF handling and session management in OAuth processes.

* 🔧 refactor: Invalidate cached tools after user plugin disconnection

- Added a call to `invalidateCachedTools` in the `updateUserPluginsController` to ensure that cached tools are refreshed when a user disconnects from an MCP server after a plugin authentication update. This change improves the accuracy of tool data for users.

* chore: imports order

* fix: domain separator regex usage in ToolService

- Moved the declaration of `domainSeparatorRegex` to avoid redundancy in the `loadActionToolsForExecution` function, improving code clarity and performance.

* chore: OAuth flow error handling and CSRF token generation

- Enhanced the OAuth callback route to validate the flow ID format, ensuring proper error handling for invalid states.
- Updated the CSRF token generation function to require a JWT secret, throwing an error if not provided, which improves security and clarity in token generation.
- Adjusted tests to reflect changes in flow ID handling and ensure robust validation across various scenarios.
