[ENG-2552] feat: confirm if read schedules should be stopped when installations exist for an integration

[RajatPawar]

Description

When a builder removes read objects from an integration YAML, we now show a confirmation prompt before deploying. This gives them a heads-up that any active read schedules for those objects will be stopped.

What it looks like:

  You are removing the following read object(s) from integration 'readSalesforce': contacts, leads
  Any active read schedules for these objects will be stopped.
  This integration has 12 installation(s).
  Installations: Acme Corp (acme-corp), FooBar Inc (foo-bar) and 10 more
  Do you still want to deploy a new revision of this integration? [y/N]

The above prompt will repeat for each integration that they are removing read objects for.

Changes

• Compares new manifest with existing revision to detect removed objects
• Lists up to 5 sample installations so builders know which customers might be affected
• Cancels deployment if they say no
• Server handles the actual schedule stopping

Testing
