Regenerates app/src/main/assets/database/app.db with the fixed build_db.py, so
the app finally ships the current question catalog. The db had drifted far from
the JSON source of truth: 6103 -> 3811 questions (the intentional 150-cap trim),
+150 quality_time (a category the app could not show at all), and daily 500 ->
511 — the 11 wildcards, whose feature (DailyModeResolver) was built but had zero
content in the db, so wildcard days were dark. Identity hash is unchanged
(7e7d78fc...), schema untouched, so no migration is involved.
Scale labels now actually render. The db stored snake_case answer_config while
the app's only parser (QuestionMapper.parseAnswerConfig) reads camelCase, so
optString("minLabel","") resolved to "" and the scale UI fell back to bare
numbers. The rebuild emits the shape the parser reads.
Adds AssetDatabaseVerifyTest (androidTest): Room opens the asset lazily, so an
app that launches proves nothing about it — the bundled db is only validated on
first DB touch, and a bad one crashes every user on a fresh install. The test
forces a real open via openHelper.readableDatabase (triggering the copy +
identity/schema check) and asserts content, no orphan category_ids, integer
depth, and the camelCase scale contract. Verified 4/4 green on a clean install
on throwaway emulator 5558; the 5554/5556 fixtures were never touched.
Also stops shipping ~6MB of dead weight: app.db.bak_q4 and app.db.bak_q5 were
tracked inside assets/, and everything under assets/ is packaged into the APK.
build_db.py was making it worse by writing its backup next to the db; backups
now go to build/db-backups/ (gitignored, outside the packaged tree) and the
stale ones are removed. APK now contains only assets/database/app.db.
