fix(dashboard): unsqueeze board on Android tablets

- Drop the tablet-tier `.board` grid rule that crammed 6 columns into
  ≤1024px viewports with no min-width, scrunching column content to
  unreadable widths. Tablets now use the default `minmax(300px, 1fr)`
  and scroll horizontally like desktop.
- Drop `maximum-scale=1.0, user-scalable=no` from the viewport meta.
  Combined with `initial-scale=1.0` those flags trigger Android Chrome
  layout bugs in multi-window mode; the Capacitor-feel justification
  isn't worth the breakage in a browser-rendered dashboard.
- Broaden the existing iOS scroll-snap stabilization in Board.tsx from
  `(max-width: 768px)` to any touch-primary device, and re-run it the
  first time tasks populate so Android tablets get the same first-cards-
  loaded reflow that mobile already had.

+Dashboard no longer renders into a small upper-left rectangle on Android Chrome in multi-window/freeform/split-screen mode. The page now re-asserts its viewport meta with the live `innerWidth` on every resize and orientation change, defeating Chrome's habit of caching `device-width` at the original screen size (which left the layout viewport wider than the actual window, so normal-flow elements clipped while position-fixed elements pinned to the full window). Also drops `maximum-scale=1.0, user-scalable=no` from the viewport meta, and broadens the existing board scroll-snap stabilization from phones to all touch-primary devices so Android tablets get the same first-cards-loaded reflow that iOS Safari mobile already had.

+Dashboard board no longer squeezes all 6 columns into the visible width on tablet-sized viewports (769–1024px). Columns now keep their 300px minimum and the board scrolls horizontally, matching desktop behavior. Previously Android tablets in portrait mode rendered columns scrunched to unreadable widths.
