Fix sidebar collapse functionality for all three layouts

- Remove manual width control that was conflicting with rail prop
- Use fixed width and rail-width props for proper Vuetify 3 behavior
- Simplify toggleDrawer function to just toggle miniVariant
- Add v-show directive to hide list groups in rail mode
- Applied fixes to admin.vue, member.vue, and board.vue layouts

The sidebar now properly collapses to 56px rail mode showing only icons,
and expands to 280px full width showing complete navigation items.
