Summary of Changes

• All Delete* processors now allow deletion only when status is Activated or Suspended.
• New integration tests verify delete-from-Suspended for Location, Exchange, Contributor, and Device.
• Delete-from-Activated paths for Link, User, and MulticastGroup were already covered by existing tests.
• No regressions: Reference-count and authorization checks remain unchanged.
• Changelog updated: Added an Unreleased note documenting the new Activated || Suspended requirement for all Delete* instructions.

Testing Verification

• All lint checks green.

Closes #2223
