Restaurant staff will now hear the new order alert repeatedly when a placed order arrives through UrbanPiper. The sound stops once the notification is closed or the Review order button is clicked, helping teams notice incoming orders faster.

In this commit:
===
- Played `order-receive-tone` sound in a loop when a new order with status
placed is received.

this sound will stop.

This update adds automated front-end test coverage for the preparation display used in point-of-sale restaurant workflows. It helps reduce the risk of future changes breaking order preparation screens, improving reliability for businesses using these features.

This commit introduces a test environment to test the preparation display front-end.

Spreadsheet screens are now better adapted for mobile use, especially when the on-screen keyboard appears. Menus that rely on side panels are hidden on mobile to avoid users tapping options that cannot be used properly on smaller screens.

AI and WhatsApp discussion features now use the shared avatar link method introduced in the core platform. This keeps contact and member images consistent across apps and reduces the chance of mismatched avatar behavior after platform updates.

This commit adapts the code to use the new member.avatarUrl getter introduced in community.
