feat: persist columns to localStorage, custom fields as columns

- Column config saves to localStorage on every change
- Load from localStorage on mount (survive reloads without saved view)
- Custom fields appear as column options in picker
- Custom field values render in ticket rows
- Backend now always includes custom_fields in GET /tickets response
