Fix tests to work with ES modules and TypeScript

- Updated Jest configuration to use ts-jest ESM preset
- Added NODE_OPTIONS flag for experimental VM modules support
- Fixed import statements in all test files to import Jest globals
- Rewrote provider.test.ts to work with ESM (using actual implementations with mock Redis)
- Fixed test expectations to match actual implementation
- Fixed encryption key generation in tests (using proper 64-char hex tokens)
- Standardized token_type to "Bearer" across codebase
- Removed unused imports to fix lint errors
- Excluded scratch folder from test runs

All tests now pass successfully with proper ES module support.
