fix(home): prevent bento grid overflow on narrow viewports

CSS grid items default min-width to min-content; the tram widget 3-col
subgrid plus its баbadges and long затем text forced its cell wider
than 1.1fr, collapsing the outer layout on tablet. Fixes:

- outer bento row → gridTemplateColumns: minmax(0, 1fr) minmax(0, 1.1fr)
- events+notes row same treatment
- TransportWidget inner subgrids: 58px → 52px badge, 1fr → minmax(0, 1fr)
- Cell: minWidth: 0, overflow: hidden, затем text trimmed with ellipsis
  and short м suffix (5м instead of 5 мин)
- big number 32→28px, badge 22→20px to fit in denser columns
