Internal logic for choosing model-access tier and entitlement was simplified and renamed

What

The internal functions that decide which model-access setting applies to a session had an explicit early-return check removed; that check and a related one are now folded into a single combined condition. Several related helper functions used for looking up enforcement, entitlement, and tier were also renamed internally.

Why

This appears to be an internal refactor of how model access and entitlement decisions are computed, without a stated change in what the outcome is for users.
