Complete LnbitsAPI migration to dependency injection pattern

- Convert LnbitsAPI from singleton to BaseService extension
- Add LNBITS_API service token to DI container
- Register LnbitsAPI service in base module with proper initialization order
- Update AuthService to depend on injected LnbitsAPI instead of singleton
- Fix BaseService to properly track LnbitsAPI dependency in getMissingDependencies
- Update events API functions to use dependency injection
- Resolve initialization timing issue preventing application startup
