Fix forecasted availability mismatch in capacity widgets

Forecasted availability widgets should reflect the same blocked-slot reality as the actual scheduling system.

Transcript Context

The team described a recurring capacity problem where certain widgets appear to lose a slot even though the slot still exists elsewhere in the system and can still be booked. They suspected a time-handling issue because the mismatch seems limited to forecast-style widgets rather than the actual available slots. The visible result is a misleading capacity chart pattern that makes revenue and staffing projections look wrong. Specifically they identified the Revenue Widget and the Capacity widget.

AJF has a Tues AM inspector meeting every other week that does not block any slots but does appear to impact the projections on these two widgets
