chore: fix tests, remove unnecessary imports

refactor: Implement permission checks for file access via agents

- Updated `hasAccessToFilesViaAgent` to utilize permission checks for VIEW and EDIT access.
- Replaced project-based access validation with permission-based checks.
- Enhanced tests to cover new permission logic and ensure proper access control for files associated with agents.
- Cleaned up imports and initialized models in test files for consistency.

refactor: Enhance test setup and cleanup for file access control

- Introduced modelsToCleanup array to track models added during tests for proper cleanup.
- Updated afterAll hooks in test files to ensure all collections are cleared and only added models are deleted.
- Improved consistency in model initialization across test files.
- Added comments for clarity on cleanup processes and test data management.

chore: Update Jest configuration and test setup for improved timeout handling

- Added a global test timeout of 30 seconds in jest.config.js.
- Configured jest.setTimeout in jestSetup.js to allow individual test overrides if needed.
- Enhanced test reliability by ensuring consistent timeout settings across all tests.

refactor: Implement file access filtering based on agent permissions

- Introduced `filterFilesByAgentAccess` function to filter files based on user access through agents.
- Updated `getFiles` and `primeFiles` functions to utilize the new filtering logic.
- Moved `hasAccessToFilesViaAgent` function from the File model to permission services, adjusting imports accordingly
- Enhanced tests to ensure proper access control and filtering behavior for files associated with agents.

fix: make support_contact field a nested object rather than a sub-document

refactor: Update support_contact field initialization in agent model
