Dashboard redesign: unified warm-console design system

[harshcodesss]

Dashboard redesign: one warm-console design system across every page

Rebuilds the six app surfaces (Home, Projects, Incidents, Report, Settings, Install) on a single shared design system, plus the backend read endpoints they need.

Design direction

"Warm console": showcase surfaces (Home, Projects) lead with warmth; working surfaces (Incidents, Report) lean into density. One orange-led palette, one set of primitives, consistent chrome everywhere.

Frontend

• Shared UI primitives: token vs. citation chips, stat tile with mini-graphs (histogram, semi-gauge, dual meter), segmented tabs, funnel select.
• Collapsible sidebar with a single orange active state; the main pane recenters as it collapses (no dead left margin).
• Home dashboard: stat row, 2:3 project-health panel + 1:3 animated new-project card, recent incidents.
• Projects rebuilt on the meetings-card pattern with tabs and sort.
• Incidents console table with live status.
• Document-first incident report: white, high-readability layout, minimally highlighted identifiers, expandable hypotheses.
• Settings (profile, report delivery toggles, active sessions) and a step-by-step install guide with a verify card.

Backend

• GET /stats/activity: per-day activity series for the home histogram.
• GET /projects: extended with health rollups (recent run statuses, incident counts, last incident time).
• GET/DELETE /auth/sessions + POST /auth/logout-all: list and revoke active sessions.
• PATCH /me: preference merge that locks delivery settings correctly.

Tests

Backend suite and ruff clean; frontend typecheck, lint, and vitest render tests green.
