Merge wilm: gevent migration, endpoint telemetry phase 2, backup/restore

Brings in 98 commits from wilm (origin/wilm @ 811e6ca61a):

Major features:
- Move API to gevent workers for better concurrency
- Endpoint agent startup jitter (prevents thundering herd)
- Complete backup/restore with restic
- Endpoint telemetry phase 2 (disk health, mapped drives, user context)
- PC Detail UI rework with new cards and tabs
- Dell Command actions and Corporate Tools tab
- Agent version column in Fleet view

Conflict resolution:
- Backup/restore: Accepted wilm implementation (10 files)
- Agent startup jitter: Accepted wilm v1.12.0
- PC Types list fix: Accepted wilm version
- Endpoint plugin domain clamping: Kept ours (defensive)
- Test files: Accepted wilm versions for consistency

Testing required:
- Verify gevent handles concurrent requests
- Test backup/restore functionality
- Verify agent startup jitter timing
- Test endpoint telemetry collection
- Validate PC Detail UI changes
