Replace the revoke functionality with delete to properly clean up agent references.
When an agent is deleted:
- All direct device assignments are removed
- Agent is removed from site defaults
- Agent is removed from organization defaults
- Devices automatically fall back to site/org agents or cloud polling
This ensures no orphaned references and provides better clarity about
what happens to device monitoring when an agent is removed.
