#262 [UI/UX] Mobile Responsiveness + Advanced Filters Polish

[RaminNietzsche]

Problem

The dashboard is desktop-first. Mobile widths break table layouts; filters (severity, KEV, EPSS, source) are client-side only on the full vuln list — no saved filter presets, no URL-shareable query state, and limited keyboard/ARIA on dense tables.

Current state

• React + Tailwind; RTL for fa/ar
• Vuln table with sort/filter in memory
• Playwright E2E on desktop viewports

Goals

• Responsive — card layout on <md, sticky filter bar, touch-friendly actions
• Advanced filters — multi-select severity/source, EPSS/KEV toggles, date range on published
• URL state — ?severity=critical&kev=1 sync with React Router search params
• Saved views — localStorage presets (tenant-scoped key)
• a11y pass: focus order, live regions for scan progress, contrast on badges
• i18n ×6 for new filter labels

Out of scope (v1)

• Full design system rewrite
• Native mobile app
