/iblai-credit

Add the SDK CreditBalance widget — a navbar dropdown that shows the user's current plan (Free / Trial / Premium), remaining and consumed credits, the next reset date, the auto-recharge configuration, and a plan-aware action button (Upgrade Plan / Manage Usage + Add Credits / Manage Billing).

The widget is shipped by @iblai/iblai-js (SDK 1.6.0+) from @iblai/iblai-js/web-containers. It is rendered as an icon button with an unread/low-credits status dot and a dropdown panel on click.

Do NOT add custom styles to the SDK component — it ships with its own styling. Do NOT implement dark mode unless asked.

Follow the component hierarchy: use ibl.ai SDK components (@iblai/iblai-js) first, then shadcn/ui (npx shadcn@latest add <name>).
