Add TestReserveSlot_DoesNotSelfBlock, TestAdminReserveSlot_DoesNotSelfBlock and TestReserveSlot_CleansUpAnonReservation. Add UserIDKey context to admin approve edit request tests. Remove weekend-day adjustment in TestAdminApproveEditRequest_OverlapWithBooking_Regression and TestAdminApproveEditRequest_EvictsPendingRelease (no longer needed).

Add OutOfHours field to AdminCreateBookingForUserRequest. When true, skip exceptional hours closed check and include out_of_hours in INSERT. Add tests verifying: bypass of exceptional closure, rejection without flag, overlap detection still works, and time blocker warning.
