POS Bookings: Set View Order as primary action button

[joshheald]

Closes: WOOMOB-2293

Description

Extracts "View Order" from the booking detail overflow (...) menu into a standalone filled button in the header, making it the primary action. This reduces the risk of accidental destructive actions (Refund, Cancel) by giving the only non-destructive action visual prominence.

• "View Order" is now a filled button to the left of the ... menu, always visible
• The overflow menu retains only the destructive actions (Issue Refund, Cancel Booking)
• The ... menu hides entirely when there are no remaining actions (e.g. cancelled, unpaid bookings)

Test Steps

1. Open POS Bookings and select a paid booking → verify "View order" button appears next to ... menu, and the menu contains only "Issue Refund" and "Cancel Booking"
2. Select an unpaid booking → verify "View order" button appears next to ... menu, and the menu contains only "Cancel Booking"
3. Select a cancelled booking → verify "View order" button appears alone with no ... menu
4. Tap the "View order" button → verify it navigates to the order detail view
