- Full UI redesign: GitHub-dark palette, custom CSS vars, better
contrast, card layout, cleaner tables and typography
- Dashboard auto-refresh every 30s (was 60s)
- Remove Quotas tab; each share row now has a Quota button that opens
a modal pre-filled with the share's valid users (SMB) or path (NFS)
- Replace all alert() with Bootstrap toast notifications
- Add Users tab: list system users (uid >= 1000) with SMB status,
create user (useradd + smbpasswd), delete user, change SMB password
- Backend: /api/users GET/POST, /api/users/<name> DELETE,
/api/users/<name>/password POST
