Customer portal navigation and invoice details

What changed

The customer portal now has route-based navigation for bookings, wallet balances, and profile details. The bookings view also includes a clear new-booking action so returning customers can start another reservation without leaving the portal context.

Portal profiles now support company and invoice details, and returning customers can reuse those details during future booking checkout. The admin schedule view also keeps booking and buffer blocks visually below sticky space and staff headings while scrolling.

Why this matters

• Customers can find bookings, wallet balances, and profile information without scrolling through one long portal page.
• Repeat business bookings are faster because invoice details can be stored once and reused.
• Studios with portal-enabled plans get a cleaner self-service experience without changing the booking workflow.
• Admin schedule review is easier because sticky headings stay readable while scrolling dense booking days.
