Add 2FA, email + password reset, and batch-7 pages

Auth (hand-built on the auth core):
- 2FA: User model gains two_factor_secret/recovery_codes/confirmed_at (+ idempotent
  MariaDB migration). authorize() requires a valid TOTP code when 2FA is confirmed
  (secret decrypted via Laravel APP_KEY, fail-closed). Two-step login (precheckLogin
  reveals the code field). /settings/2fa enable/confirm/disable flow.
- Password reset: nodemailer email service; PasswordReset model + migration;
  /forgot (request, generic response) + /reset (token sha256 + 1h TTL, sets argon2id
  hash). Login links to forgot.

Batch 7 (parallel agents): /admin/commandocentrum (RCON controls + emulator_errors),
social write actions (friend request + guild forum new thread), /help/[category],
/badges (public). env: APP_KEY, APP_URL, SMTP_*. Nav extended.

Verified: tsc exit 0, vitest 48/48, next build exit 0 (64 page routes).
