feat(frontend): slice 8 — remove MUI/@emotion deps + update REQUIREMENTS
Web UI rework. Final slice.
- Remove from package.json: @mui/material, @mui/icons-material,
@mui/x-data-grid, @emotion/react, @emotion/styled (zero consumers
remain in src after slices 1-7b; grep-verified).
- Update docs/REQUIREMENTS.md (+63 lines): single design system
(shadcn/ui + Tailwind v4 + lucide-react), thin-dashboard observability
model (no in-app charts; Grafana deep-links), TanStack tables
(visibility-only parity), reconciled IA (Backups top-level nav;
Media at /media with /applications redirect), repurposed chart-*
status cues, removed deps list.
- Note: AGENTS.md 'node --test tests' invocation is a pre-existing
broken command (treats tests/ as a module); correct form is
'node --test' (auto-discover, 5/5 pass) — verified identical at
pre-rework baseline ef5311b.
Gate: build + lint + vitest (23/64) + node --test (5/5) green.
Web UI rework complete.
