Phase 2 frontend: Add React components for band invite management

Components created:
- InviteManagement.tsx: List pending invites, revoke functionality, copy links
- UserSearch.tsx: Search users to invite, role selection
- web/src/api/invites.ts: API wrappers for new endpoints
- web/src/types/invites.ts: TypeScript interfaces

UI enhancements:
- BandPage.tsx: Integrated new components, admin-only sections
- Members section now includes invite management for admins
- Search component for finding users to invite

Features:
- Admin can list, view, and revoke pending invites
- Copy invite links to clipboard
- Search existing users to invite (excluding current members)
- Real-time invite status (pending/expired/used)
