- Extract email and chatgpt_subscription_last_checked from codex JWT in
addition to plan_type and subscription_active_until.
- Settings → 계정 row now displays: email · plan badge · expiry badge
with active/soon/expired color coding (green/amber/red).
- Fix codex/.codex-accounts directory scan picking up sibling dirs like
"1.bak-..." and double-counting an index (require dirname to be
fully numeric).
Motivation: rotation was landing on accounts whose Pro/Team subscription
had silently expired, causing OpenAI to reject upper-tier models with
a misleading "model not supported" error. Surface expiry in the UI so
the user can see at a glance which accounts need renewal.
