Lets an availability gate read what Box Office entitles the tenant to, without merging modules and audiences.

Added

• Cratis.Showrunner.BoxOffice.Product.Availability: AddBoxOfficeEntitlementsAvailability() supplies the host-provided context value entitlements (provide entitlements Entitlements from host), readable in available when conditions as the tenant's active state, readOnlyReason, seats and each module's level (None, Preview, Trial, Full) and usable (Expose Box Office entitlements as a host-provided context value #127)
• Documentation on using entitlements in availability conditions and how Box Office modules relate to GuestList audiences

Reviewer notes

• Placement: the provider is a new package, BoxOffice.Product.Availability, mirroring GuestList.Availability, so BoxOffice.Product (and every product using it) takes no Choreography/Orleans dependency. No existing Box Office code changed.
• Tenant scope: the engine's catalog and IHostContextValues are singletons while IEntitlements is scoped, so the value reads IEntitlements from IHttpContextAccessor.HttpContext.RequestServices. Outside a request it throws (failure, not denial).
• Levels are text ("Full") because the engine's equality does not compare an enum against text.
• Unknown module id is absent, so the gate is Unknown and denies.
• Local: Debug build/specs (net10.0 and net11.0, 26 passed) and Release build, zero warnings. The PR body checker hook script could not be run from my shell (blocked by a guard); the body follows the allowed shape.
