Issue #3611921: Expose workflow profiles in the booking admin UI

Adds the missing Booking admin menu links for the workflow profiles list and the workflow settings page, and a Workflow profile picker on the resource type and tenant forms. The picker is added by yoyaku_orchestra altering the yoyaku_ui forms and stored as a third-party setting, the key the resolver reads, so yoyaku_ui keeps no dependency on the workflow. Kernel-tested (field injection on both forms, persist/clear round-trip, preselection).
