feat: server members API + member list in sidebar + fix chat input

Backend:
- Add GET /api/v1/servers/{serverID}/members endpoint
- Wire MemberHandler routes in main.go

Frontend:
- Create member store (fetchMembers by server ID)
- MemberList now fetches members from API instead of empty props
- ChatArea: show channel name instead of ID, add error display,
  add flex-1 + min-w-0 to input for proper sizing, error handling
  on sendMessage
