fix(api): remove type-only imports of injectable classes to fix NestJS DI

Type-only imports (`import { type X }`) strip runtime type metadata
needed by NestJS dependency injection via reflect-metadata. This caused
`UnknownDependenciesException` errors where constructor parameters
resolved to `Function` instead of the actual class.

Fixed 129 files across all modules:
- Services (LoggerService, PrismaService, CacheService, etc.)
- CQRS buses (EventBus, QueryBus, CommandBus)
- DTOs used with @Body()/@Query() decorators in controllers
- Payment gateway services and search repositories

Also fixed E2E test infrastructure:
- auth.fixture.ts: use destructuring pattern for Playwright fixture
- global-teardown.ts: correct column names (Lead.agentId, Transaction.buyerId)
- inquiries.spec.ts: flexible response property checks
- payments-callback.spec.ts: accept 500 for unknown provider

All 111 API E2E tests now pass.
