feat(backend): remove auto loyalty redemption from booking progress

Browse Source 
Remove auto-apply of pending loyalty redemption during ProgressBookingHandler. Now only checks if loyalty was applied on this booking (via booking_discounts) to skip stamp award. Redemption is purely manual via ApplyLoyaltyRedemption. Use LoyaltyStampCost constant instead of hardcoded 10.

Ultraworked with [Sisyphus](https://github.com/code-yeongyu/oh-my-openagent)
