Dashboard layout: Apps card header (R-909), launcher header wraps on a phone (R-907), overflow counted after the page filter (R-906)

- Apps card: title row (logo top-aligned, name, address cut with an ellipsis and full in title) over a wrapping
  .stack-tags row; the tags no longer share a space-between row with the name.
- Phone (768px block): .page-header wraps; the share button drops to its own line, text whole.
- GetBannerAlerts(page, lang): the layout's filter before the cap; baseData and /monitoring use it.
- Tests: TestStackCardHeaderLayout, TestR907_PageHeaderWrapsOnAPhone, TestR906_* (all red against 05e12921).
- No Hungarian string changed. The three stacks parity fixtures are re-captured in the next commit
  (this commit alone fails TestI18nParity on them; both are pushed together).
