fix: price sorting by period type, pagination, avgRating on dashboard

- Sort by monthlyPrice when periodType=MONTHLY instead of always dailyPrice
- Fix client-side pagination in MyBookingsPage and LandlordListingsPage
- Compute avgRating in /rentals/mine endpoint so dashboard shows ratings
- Fix falsy filter for avgRating=0 on landlord dashboard
