Audit and fix NPC, door-staff and UI dialogue

- Route the Reason verb through authored reason contexts and give every shared archetype an in-character answer.
- Add Hollywood wristband and TV Studio ticket/credential door-staff lines.
- Clarify radio cancellation, Ask terminology, start hints and campaign-reset copy.
- Record the dialogue audit and length findings in docs/ui-copy.md; add regression tests.
