feat(uat-batch-10): copy polish, TTL trim, and a11y discrete fixes

- Supplemental-info link TTL trimmed from 30 → 14 days (single
  constant in supplemental-forms.service).
- LinkedBerthsList toggle renamed "Mark in EOI bundle" →
  "Include in EOI"; tooltip aria-label updated to match.
- Icon-only row-action triggers on the interest / client / berth list
  tables gain aria-label (Row actions for <name>) so SR users hear
  the row context.
- Table / Board view toggle on interest list gains aria-label +
  aria-pressed on each variant; wrapper gets role="group".
- Upcoming-milestones disclosure on interest-tabs gains
  aria-expanded + aria-controls; recommender Hide/Add filters
  button matches.
- BrandedAuthShell logo alt no longer defaults to "Sign in" — uses
  the configured `appName` when known, empty string otherwise so
  screen readers don't announce "Sign in" on password-reset /
  set-password pages.

tsc clean. 1419/1419 vitest pass.
