feat: implement TimeSafari integration services and improve code quality

- Add DailyNotificationService with circuit breaker and rate limiting - Add DatabaseIntegrationService with watermark management - Add TimeSafariIntegrationService with DID/VC support - Add TimeSafariCommunityIntegrationService with rate limiting - Add PlatformServiceMixin for Vue component integration - Add comprehensive TimeSafari integration example - Fix all linting issues (133 → 0 warnings) - Add .eslintignore to exclude dist/ from linting - Replace console statements with proper error handling - Replace 'any' types with 'unknown' for better type safety - Add explicit return types to all functions - Replace non-null assertions with proper null checks All tests passing (115 tests across 8 suites)
