Phase 6: the UI for the Phase 5 provisioning backend.
- CreateGameAccountForm: reusable game-account form (own username + password),
mapping the sidecar errors (409/429/403/503) to friendly messages. Wired into
GameAccounts (self-serve) — shown alongside the [link flow when the
game_account_signup flag is on (exposed via public settings), so a registered
player can create + link a game account from their portal.
- Admin Invites view (/admin/invites, admin-only): send an invite at a chosen
access level, list invites with status, revoke pending ones. When email isn't
configured the create response's accept link is surfaced to copy manually.
- Public accept page (/invite/:token): validates the invite, sets username +
password (email + role pre-assigned), creates the account at that role and logs
in; for a player invite it then offers the built-in "create game account" step
before the portal. Honeypot-guarded like registration.
- Admin unlink wired into UserDetail via GameAccounts (per-account Unlink button,
confirm + reconcile).
- Backend: expose gameAccountSignup availability in public settings.
Client build clean; server 193/193.
