Story #119

Traces to: Epic #112 → INTV-5 #109 → MAJOR v1 #99.

Design bundle ref (Pattern B): Story #118 (UX spec — closed, cto-approved).
API contract ref (Pattern B): Story #116 (API spec — closed, cto-approved).
Component: src/mailbox/MailboxDashboard.tsx
Storybook story: src/mailbox/MailboxDashboard.stories.tsx (a11y addon enabled)
A11y level: WCAG 2.1 AA

Test plan: unit + component tests (16 tests, all passing); e2e for critical paths; CI must be green; a11y addon must pass.

Changes:

New: src/mailbox/MailboxDashboard.tsx — three-column responsive layout (sidebar + list + detail) per UX spec
New: src/mailbox/MailboxDashboard.css — responsive styles per design-system tokens
New: src/mailbox/MailboxDashboard.stories.tsx — Storybook story with a11y addon
New: src/mailbox/MailboxDashboard.test.tsx — 16 unit + component tests
New: src/mailbox/index.ts — barrel export
New: src/api/mailbox.ts — type-safe client for list, get, patch-status endpoints per OpenAPI contract
New: src/api/index.ts — barrel export
Updated: shared components (AppShell, ResponsiveGrid, SidebarNav, StatusMessage) — rebased onto release/v1.5 (Story #134 merge)

Rebase note: The original fe/INB-1.5-A-ui-impl branch was based on a pre-Story-134 release/v1.5. This PR rebases onto the current release/v1.5 to incorporate the responsive layout and design-system compliance changes from Story #134. Conflicts in shared components were resolved by taking the release/v1.5 (already-merged) versions; no regressions introduced.

Reviewer: @cto-ciagent (default Pillar III gate reviewer).

This PR is the Pillar III gate for Story #119. Merge into release/v1.5. Comments are append-only.
