gui: every screen lays itself out to fit, down to a 360-point tiling slot

Narrow windows overlapped and clipped: the top bar's crumb, date, and
search ran into each other; big numbers wrapped mid-figure; tables
painted columns over each other; the entry and document panes squeezed
their lists to slivers; anything too wide widened the whole page.

- Below 1000 points the sidebar becomes an icon rail (names, attention,
  and integrity checks in tooltips).
- The top bar lays out right to left: search shrinks to its icon, the
  date drops, the crumb truncates.
- Pages are pinned to the window width with narrower margins when tight,
  so one wide thing can't push everything off screen.
- Tiles (KPIs, cash accounts, documents) fit as many columns as the
  width allows, balanced across rows; KPI figures shrink rather than wrap.
- Painted tables shrink their amount columns, clip labels with an
  ellipsis, then scroll sideways rather than overlap.
- List/detail splits show only the detail when both won't fit.
- Reports: the side list becomes a picker; controls wrap by known width.
- Smaller fixes: chart labels thin out, company facts stack, journal
  timestamps yield, transaction filters become a dropdown.
- Min window size drops to 360x400; the screenshot test covers every
  report, a register, a document, and a journal event.
