fix(api): resolve NestJS DI + ValidationPipe bugs from type-only imports

- Remove `type` modifier from imports used as DI constructor params
  across ~235 files (@Injectable, @Controller, @Module, @Catch,
  @CommandHandler, @QueryHandler, @EventsHandler, @WebSocketGateway).
  TypeScript emitDecoratorMetadata strips type-only imports, leaving
  Reflect.metadata with Function placeholder and breaking Nest DI.
- Fix controllers: DTOs used with @Body/@Query/@Param must be runtime
  imports so ValidationPipe can whitelist properties. Previously
  returned 400 "property X should not exist" on every request.
- Register ProjectsModule in AppModule (was defined but never wired).
- Add approve()/reject() methods to TransferListingEntity referenced by
  ModerateTransferListingHandler.
- Export BankTransferConfirmedEvent from payments barrel for
  subscription activation handler.
