Fix ~60 compile errors - build now succeeds
- Fixed DI imports: javax.inject -> dev.zacsweers.metro - Fixed cardano-client-lib API: KoiosBackendService constructor, Amount.quantity type - Added kotlin-parcelize plugin - Workaround for Timeline.sendRaw(): use message prefix approach - Fixed MnemonicCode wordlist access - Fixed Compose lifecycle/context handling - Updated test fakes BUILD SUCCESSFUL - unit tests still need updating for new APIs
