Create the CMS-owned feature tables in the live DB (amx_test)

The live DB lacked 32 tables the conversion's own CMS features need
(radio_*, game_*/challenges, staff_activities, alert_logs,
email_templates, social_accounts, website_article_comments/reactions).
Generated idempotent CREATE TABLE DDL from `prisma migrate diff`
(CREATE statements ONLY — every ALTER/DROP excluded so no emulator-owned
table is ever touched), as migration 0004. Applied to amx_test via the
existing idempotent runner.

0005: radio_listener_points shipped as a stub (id+timestamps); the
/radio/leaderboard raw query needs user_id + points, so add them (model +
ALTER migration).

Verified against amx_test: drift check now reports 0 missing modeled
tables (live tables 255 -> 287), and a full route sweep logs ZERO
prisma errors (radio/leaderboard + all radio pages 200). tsc 0,
vitest 49/49, next build 0.
