Chats list: show balance & subscription for Telegram-linked accounts

- SponsorHelper now caches balance, expire_at, plan and telegram_linked
  from /mobile/me (keyed by Telegram id)
- New FoxAccountInfoCell: balance on the left, subscription days left on
  the right, shown as the first row above 'Archived chats'
- Only visible when the Telegram account is linked to GhostCloud/FoxCloud
- DialogsActivity refreshes on resume and updates the row on change
