✅ All reported bugs fixed and verified

## Bug #1: Recent Logins Missing Usernames

**Reported**: "Recent Logins hat keine user name drin!"

**Root Cause**: 
- Frontend was looking for `login.user` field
- Backend API returns `login.username` field (different name)

**Fix Applied**:
- Updated `frontend/app/identities/page.tsx` line 559
- Changed to: `(login as any).username || (login as any).user`
- Added fallback for compatibility

**Verification**:
```
Backend Response: {"username":"administrator","login_str":"Wed Apr 15 22:45 2026"}
Frontend Now Shows: → administrator (Wed Apr 15 22:45 2026)
Status: ✅ FIXED
```

## Bug #2: File Properties Owner – No Name Autocomplete

**Reported**: "File Properties Owner macht keine vervollständigung der namen"

**Root Cause**:
- Owner input field was plain `<input type="text">`
- No autocomplete or data suggestions
- Users had to type UID numbers or guess names

**Fix Applied**:
1. Added state variables to track available users/groups:
   ```typescript
   const [usernames, setUsernames] = useState<string[]>([])
   const [groupnames, setGroupnames] = useState<string[]>([])
   ```

2. Added `loadUsersAndGroups()` function to fetch from API:
   - Calls `/api/identities/users` on component mount
   - Calls `/api/identities/groups` on component mount
   - Extracts username and groupname arrays

3. Updated Owner input field:
   ```html
   <input list="owners-list" ... />
   <datalist id="owners-list">
     {usernames.map(name => <option key={name} value={name} />)}
   </datalist>
   ```

4. Added same for Group field

**Verification**:
```
Available Users: root, administrator, testuser, wsdd2, nobody
Available Groups: root, sudo, administrator, tape, ...
Owner Dropdown: ✅ NOW shows autocomplete
Group Dropdown: ✅ NOW shows autocomplete
Status: ✅ FIXED
```
