Missing Scheduler of Public APP

[stefangutica]

Reasoning

• each individual app must have its own scheduler imported at the root module
• each individual app must have its event emitter imported at the root module

Proposed Changes

• import ScheduleModule and EventEmitter at each individual app root module

How to test

• dependency errors should disappear

Pull request overview

This PR moves scheduler and event-emitter initialization from the shared metrics module into individual Nest app root modules so each bootstrapped app has its own dependencies registered.

Changes:

• Adds ScheduleModule.forRoot() and/or EventEmitterModule.forRoot({ maxListeners: 1 }) to app and worker root modules.
• Removes EventEmitterModule.forRoot() from ApiMetricsModule.
• Aligns cron, websocket, queue, pub/sub, and API root modules around explicit event-emitter registration.
