fix(pipelines): size columns to fill, batch stage saves, inline delete confirm

Sizing:
- Board columns grow to fill wide viewports (flex-1 basis-[260px])
  instead of being capped at 300px; still overflow-scroll on narrow screens.
- Analytics grid: 2 cols mobile → 3 cols sm → 6 cols xl (was lg, which
  cramped labels on 1024-1280px widths).

Senior-review pass:
- pipeline-settings handleSave: replace N sequential UPDATEs in a for-loop
  with a single upsert (onConflict: "id"). Previously latency scaled
  linearly with stage count; now constant.
- deal-form delete: swap window.confirm for an inline confirm row that
  matches the app's pattern (pipeline-settings uses the same inline
  confirmation for pipeline deletion).
- pipeline-board: add KeyboardSensor alongside PointerSensor so deal cards
  are draggable via keyboard for a11y (Space to pick up, arrows to move).
