test: Phase 5 verification scripts and opt-in e2e integration spec

Adds scripts to seed scenario data, create Proclamations, snapshot schedules,
drive the Kiosk-facing HTTP endpoints, and an opt-in (P5_INTEGRATION=1)
Vitest spec exercising create/type/copy against a scratch database. The
integration spec is skipped by default so the normal suite needs no DB.
