feat(bitdefender): complete Network module (build-out 3/N)

- Completed Network module for bitdefender skill (GravityZone Public API)
- Added getEndpointTags (read), setEndpointLabel (gated), createReconfigureClientTask/reconfigure (gated)
- Confirmed createUninstallTask, getEndpointsByPolicy, getManagedEndpointDetailsByIp, createScanTaskByMailboxes not found under /network
- Fixed endpoint-tags renderer to handle list result (previously crashing _print_kv)
- raw gates setEndpointLabel; reconfigure already gated
- selftest 55 -> 60 passing
