feat(uat-b2): visual breakpoint fixes + form-error UX rollout

B2 Wave A (visual breakpoints):
- Documents Hub folder rail: widen ResizablePanel default 20→22%,
  min 14→18%, add min-w-[180px] CSS floor so names don't truncate
  at tablet 768
- Website analytics KPI tiles: switch lg grid 6→3 cols, restore 6
  at xl so "Visit duration" stops truncating in the 1024+sidebar
  layout
- Pipeline Value tile per-stage rows: compact $3.5M format on
  sm- breakpoint (responsive sm:hidden / hidden sm:inline pair)

B2 Wave D (form-error UX rollout):
- useFormScrollToError + FormErrorSummary wired into 5 high-impact
  forms: client-form, interest-form, yacht-form, company-form,
  berth-form. Validation failures now scroll the first errored
  field into view + render a top-of-form summary banner when ≥2
  errors exist. Remaining ~23 form surfaces queued for follow-up.

B2 Wave B (Umami follow-ups):
- TopList primitive: add onExpandRange + expandRangeLabel props
  for the empty-state nudge ("Try last 30 days" button). Callers
  can opt in to drive the page-level DateRange.

B2 Wave C (FieldLabel + admin tooltip audit):
- Verified FieldLabel primitive already exists + is adopted in
  custom-field-form. Registry-driven-form renders entry.description
  inline below labels for every entry — the broad sweep across
  15-20 admin pages is deferred to a focused polish session.
