chore: remove deprecated standalone pages and routes

[Serokz]

Summary

Following the successful integration of the tabbed Settings page (PR 4) and the unified Analysis hub (PR 5), this cleanup PR removes the deprecated standalone pages (OTA, Autotune, Scales, etc.) and deletes their legacy redirect routes.

What's Changed

• Files Deleted: Removed web/src/pages/OTA/index.jsx, web/src/pages/Autotune/index.jsx, and web/src/pages/Scales/index.jsx.
• Routing & Nav Cleanup: Cleaned up the lazy imports and router definitions in web/src/index.jsx to reduce chunk counts, leaving only the new unified routes.

This is the final phase of the frontend modernization and cleanup effort.

📝 Walkthrough

Walkthrough

Three web UI page components (OTA, Scales, Autotune) are deleted entirely. Their navigation entries, lazy-load declarations, and router routes are removed from Navigation.jsx and index.jsx. Separately, scripts/auto_firmware_version.py replaces datetime.UTC with datetime.timezone.utc for Python compatibility.

Poem

🐇 Hop, hop! Three pages gone away,
OTA, Scales, Autotune — cleared today.
The nav grows tidy, routes trimmed neat,
And timezone.utc makes the clock complete.
Less code to hop through — what a treat! 🌿
