Fix TypeScript build errors

- Remove unused imports in invites.ts
- Fix InviteManagement component (remove unused props, unneeded code)
- Fix BandPage.tsx (remove currentMemberId, remove UserSearch for now)
- Remove unused imports in types/invite.ts

Build errors resolved:
- TS6133: unused variables
- TS2304: missing variables
- TS2307: module not found

Note: UserSearch temporarily disabled - needs backend support for listing non-members
