Replicate Billing Dashboard Page

Goal

Rebuild the existing /web/app/dashboard/billing page inside /src/app/dashboard/billing with equivalent UI and behavior while adapting the implementation to the current src architecture.

Requirements

• Preserve the billing page content, layout, plan cards, checkout interaction, and checkout-return cleanup behavior from the web implementation.
• Do not copy the web structure verbatim when it conflicts with the src conventions.
• Reuse existing src/api, src/store, and utility wrappers whenever they cover the needed behavior.
• Keep route-local UI, hooks, styles, and types inside src/app/dashboard/billing.
• Keep async actions guarded by loading states and defensive error handling.

Acceptance Criteria

• /dashboard/billing exists under src/app.
• The page renders without TypeScript or build errors.
• Billing-related API calls use existing request helpers and stores where applicable.
• The checkout return cleanup mirrors the current behavior from web.
