Covers model returns data (covers * spend) but if resos spend settings are
absent the result is zero, which previously bypassed the DOW fallback. Now
fall back to DOW when the covers-based dry or wet is zero.

When forecast_rooms_for_date throws inside covers_model, asyncpg aborts the
whole transaction. The exception was being caught with a warning but no rollback,
so every subsequent query in the same request failed. Added db.rollback() in
all three exception handlers (breakfast pickupv2, dinner pickupv2, per-day loop)
and moved public.py's rollback into a finally block so it always fires even
when covers_model returns normally with a corrupted transaction.

When forecast_covers_range or forecast_revenue_for_date throw DB exceptions,
the swallowed exception leaves the async session in an aborted transaction state.
Subsequent queries (DOW averages, per-date accom) then fail with
InFailedSQLTransactionError. Adding db.rollback() in the except blocks
resets the session so the fallback path can continue cleanly.

The table is newbook_occupancy_report_data (per-category rows). Aggregate
SUM(available - maintenance) WHERE category_id != '5' to get the correct
available room count excluding overflow and maintenance.

Replace static system_config.total_rooms (80, includes overflow) with
per-day available_rooms from daily_occupancy table. This ensures
occupancy % is calculated against the correct base (non-overflow rooms)
consistent with how the rest of the app reports occupancy. Falls back
to system_config.total_rooms when daily_occupancy has no data for a date.
Also adds available_rooms per-day to the response payload.
