Add client-side spell column sorting and improve inventory search

- Implement client-side sorting for all columns including spell_names
- Add computed_spell_names CTE for server-side sort fallback
- Add resizable columns with localStorage persistence
- Add Cloak slot detection by name pattern
- Increase items limit to 50000 for full inventory loading
- Increase proxy timeout to 60s for large queries
- Remove pagination (all items loaded at once for sorting)
