fix(home): drop greeting date; fix touch scroll; tokenize TopBar icons

- Removes the date label from the greeting row (user request — тoo dense
  on tablet and redundant with TopBar clock).
- Scrolling: drops overflowY: auto on the inner Events/Notes cards and
  removes flex: 1 / minHeight: 0 from their grid. On iPad-class touch
  nested scroll containers fought the root scroll; now only the root
  scrolls, which the browser handles natively.
- TopBar: replaces hardcoded rgba(255,255,255,X) on sensor icons, chip
  background, chip border and header bottom-border with semantic tokens
  (--text-tertiary, --surface-2, --border-subtle, --hairline) so the
  thermometer/humidity/wind icons are visible in light theme.
