fix: complete rewrite of AdminUserRestrictionsPage

Fixed all reported bugs:
1. Initial values now correct (empty = no override, not defaults)
2. Save/Reset buttons always visible (fixed bottom bar)
3. Toggle buttons work correctly (can be toggled multiple times)
4. Simplified table columns (removed confusing Tier-Limit/Aktiv/Aktion)

New logic:
- Empty input = no override (user uses tier standard)
- Value entered = override set
- Change tracking with 3 actions: set, remove, toggle
- Clear status display: "Override aktiv" vs "Tier-Standard"

Simplified table structure:
- Feature (name + type)
- Override-Wert (input/toggle)
- Status (has override yes/no)

Better UX:
- Placeholder text explains empty = tier standard
- Status badge shows if override is active
- Fixed bottom bar always present
- Buttons disabled only when no changes
- Legend explains all input options
