fix: 4 bugs — MSK today events, settings scroll, note dates, persistent notes volume

- calendar API: today/week ranges use Moscow time (UTC+3) instead of UTC — previously today events did not appear until 03:00 MSK
- settings tab: add -webkit-overflow-scrolling: touch + touchAction pan-y for tablet scroll
- NotesTab: add date picker (pinDate) in editor header + date badge in list
- home: pinnedNotes now filters by pinDate (today or future), falls back to latest
- notes/auth: storage moved from /tmp to /data (falls back to /tmp if /data missing)
- deploy workflow: mount /opt/digital-home/smart-home-tablet-data:/data so notes survive redeploys
