Merge develop → main: wizard Features step + kiosk v1.7.16 fixes

Step 5 del wizard ora mostra 4 toggle (pre-compilati se già configurati):
  - Salvaschermo orologio (screensaver_enabled)
  - Prezzi lista spesa (price_enabled)
  - Piano pasti (meal_plan_enabled)
  - Suggerimenti zero-waste durante cottura (zerowaste_tips_enabled)

Solo i toggle NON ancora impostati in prefs partono da false (fresh install).
Tutti e 4 vengono salvati in SharedPreferences e inviati al server via
save_settings al completamento del wizard.

PHP/JS: zerowaste_tips_enabled aggiunto come impostazione server-side
(ZEROWASTE_TIPS_ENABLED in .env), sincronizzata nel WebView via
_applySyncedSettings() al caricamento.

 - **Recipe scraps tips** — During cooking steps, detect "waste" generated (peels, cores, bones, eggshells, coffee grounds, citrus zest, etc.) and surface AI-powered tips on how to reuse them (compost, natural cleaner, broth, candied peel, etc.). Could be shown as an optional collapsible hint card below the step that generates the scrap.
 
+## [1.7.22] - 2026-05-17

+### Fixed
+- **DB name corrected** — `health_check` now looks for `evershelf.db` (was wrongly looking for `dispensa.db`). Auto-migration included: if `evershelf.db` is missing but `dispensa.db` exists, it is renamed automatically on startup.
+- **Removed legacy `data/dispensa.db`** — the old database file has been deleted; only `evershelf.db` is used.
+- **Conditional checks** — Bring!, TTS, Scale and Internet checks only run when the respective feature is enabled in `.env` (no more false ❌/⚠️ for unconfigured features).
+- **Backups check** — no longer checks if `data/backups/` is writable by www-data (cron writes as root). Now checks that backup files actually exist and the most recent one is recent.
+- **Bring! token check** — reads `data/bring_token.json` file instead of looking for a non-existent `BRING_ACCESS_TOKEN` env var.
+
+### Changed
+- **Warning popup with 5s countdown** — when non-critical checks fail at startup, a styled popup appears showing each warning with its label and a plain-language hint explaining the problem. A countdown bar auto-closes the popup after 5 seconds, then the app starts normally.
+- **Error blocking popup** — when critical checks fail, a clear blocking panel shows with title "Errore critico", each failed check listed with its explanation hint, and a Retry button. The app does not start.
+- **`db_legacy` check added** — warns (optional) if the old `dispensa.db` file is still present alongside `evershelf.db`.
+- **32 total checks** — added `db_legacy`, `tts_url`, `scale_gateway` to the check set (conditional).
+- **Hint messages** — every check now has an Italian-language `hint` field explaining what is wrong and how to fix it.
