Shell: move Projects/News/Calendar into ShellRoute so the NavigationRail
persists across all screens. Show all 6 nav destinations on tablet
instead of 3+More overflow. Phone bottom nav unchanged.
Chat: master-detail layout on tablet — conversations list (320px) with
inline chat panel. Tapping a conversation updates state instead of
pushing a new route.
Knowledge: responsive grid (2 cols portrait, 3 cols landscape) with
card layout showing icon, title, body preview, and tags. Fix snippet
data — read json['snippet'] which the API actually sends. Bump snippet
length from 120 to 200 chars. Tasks now show description as snippet.
News: responsive grid with the same breakpoints. Larger snippet
(5 lines) in grid mode via snippetMaxLines parameter.
Briefing: centered reading column (maxWidth 700) on wide screens,
matching the web UI layout.

Tasks are not part of the knowledge API (backend rejects type=task).
When the Tasks tab is selected, fetch from /api/tasks and convert to
KnowledgeItem. Also removes per-type counts from tab labels to prevent
tabs from awkwardly resizing when counts load.
