feat(uat-batch): Group A quick-fixes — 7 items shipped, 5 verified pre-shipped

Sweeps Group A of the 2026-05-21 remaining-plan. Several items the
plan listed as open turned out to already be shipped (annotation gap
in the master doc) — those are confirmed in the commit notes.

Shipped now:
  A1  Documenso settings: collapsed `V2_FEATURE_FIELDS` +
      `CONTRACT_RESERVATION_FIELDS` (legacy SettingsFormCard) into
      `RegistryDrivenForm` sections (`documenso.behavior` +
      `documenso.templates`). Every Documenso setting now flows
      through the registry path that surfaces the env-fallback /
      port / global source badge per field. EOI generation card
      retitled to "Templates & signing pathway" since it now covers
      EOI + reservation + contract template IDs (registry already
      had all three under `documenso.templates`).
  A2  WatchersCard empty state: bumped `mb-3 → mb-4 pb-1` so the
      "No one is watching yet" line has breathing room above the
      "Add a watcher…" select.
  A4  /invoices/upload-receipts guide copy: terse luxury-CRM tone.
      Drop "Snap a photo", "fancy phone camera", "No typing. No
      spreadsheets." Tighten OCR explainer to one sentence;
      action-oriented step + best-practices headers.
  A5  Pageviews chart X-axis: added `interval="preserveStartEnd"` +
      `minTickGap={52}` so multi-week ranges thin out the middle
      ticks instead of overlapping. The MM-DD formatter was already
      in place from an earlier session.
  A7  Inbox doc comment: was stale ("Alerts first, Reminders
      second") but the JSX already had Reminders before Alerts.
      Fixed the docstring.
  A9  CommandList scroll-cap: `max-h-[300px]` now `max-h-[min(300px,
      var(--radix-popover-content-available-height,300px))]` so the
      cmdk list never extends past the host Popover's available
      area. Non-Popover hosts fall through to the 300px static cap.
  A10 DropdownMenuContent: `max-h-96` now
      `max-h-[min(24rem,var(--radix-dropdown-menu-content-
      available-height,24rem))]` for the same available-space
      behaviour on long menus near the viewport edge.
  A11 Residential InterestsTab (list page): row gets an onClick →
      `router.push`; first-cell Link stops propagation so middle-
      click / Cmd-click "open in new tab" still works.
  A12 StageStepper: gained a stage-name row below the bar showing
      every reached stage's short label inline (muted for future
      stages). `size="xs"` variant keeps the cramped table-cell
      footprint intact (no labels).

Already shipped (just annotation gap in master doc):
  A3  EOI "Mark as signed without file" button — line 599 of
      interest-eoi-tab.tsx, parent passes onMarkSigned. Master doc
      already has `SHIPPED in 52342ee` annotation.
  A6  Pageviews vs Sessions explainer — Info popover at line
      157-181 of website-analytics-shell.tsx.
  A8  BulkAddBerthsWizard CurrencySelect — line 376 (apply-to-all)
      + line 456 (per-row).

Verified: tsc clean, vitest 1454/1454.
