Add Sync All buttons functionality for server matrix

WHAT WAS DONE:
- Added POST /admin/servers/sync-all/:node endpoint
  - Accepts 'tx1' or 'nc1' as node parameter
  - Syncs whitelist to all servers on that node
  - Returns count of synced/errors

- Wired up buttons in index.ejs with htmx
  - hx-post to the new endpoint
  - Results display in #sync-result span

Files changed:
- services/arbiter-3.0/src/routes/admin/servers.js (+45 lines)
- services/arbiter-3.0/src/views/admin/servers/index.ejs
