Add server-side unit tests for LND invoices and common utilities

- Add Jest configuration for server-side TypeScript tests
- Add tests for extractKeysendMessage function in LND invoices controller
  - Tests cover keysend message extraction from htlc custom_records
  - Tests verify the PR fix for returning memo when no keysend message exists
- Add tests for CommonService utility functions
  - maskPasswords: password field masking
  - convertTimeToEpoch/convertTimestampToTime: time conversion
  - sortAscByKey/sortDescByKey: array sorting utilities
  - titleCase/camelCase: string formatting
  - isVersionCompatible: version comparison
  - getRequestIP: IP extraction from request
  - getMonthDays: calendar utilities
- Add npm scripts: test:server and test:server:coverage
