refactor(#292 review): extract NAVBAR_COLLAPSE_BREAKPOINT constant (F2)

The AppShell navbar breakpoint and both burger toggles' hiddenFrom/visibleFrom
must be equal, or the sidebar becomes unreachable on tablet widths (the round-1
regression). A comment guarded that before; now a shared const does. Add
NAVBAR_COLLAPSE_BREAKPOINT='md' to sidebar-atom.ts and reference it from the navbar
breakpoint (global-app-shell) + both toggles (app-header). aside.breakpoint and the
sm brand/search gates are intentionally separate contracts, left untouched.

+- **Place several images side by side in a row.** A new "Inline (side by
