Fix navigation drawer collapse functionality in all layouts

- Replace dynamic width binding with static width and rail-width props
- Remove Vuetify 2 pattern (:width="miniVariant ? 56 : 280")
- Add Vuetify 3 compatible props (width="280" rail-width="56")
- Applied fix to admin.vue, board.vue, and member.vue layouts
- Sidebar now properly collapses to rail mode when toggled
