chore(web): bump every dependency to latest

Bumped via `bun update --latest` then resolved breakage from two
major-version jumps:

1. Next.js 15.5 → 16.2 + @next/eslint-plugin-next 16: dropped the
   `flatConfig` namespace. Updated web/eslint.config.mjs to use
   `nextPlugin.configs["core-web-vitals"]` per the new export shape.

2. lucide-react 0.553 → 1.x: lucide upstream removed all brand icons
   (Github, etc.) — they are now expected to come from a separate brand
   icon library. Pinned lucide-react at the last 0.x (0.577.0) for now;
   migrating to a brand-icon library is tracked as a follow-up.

All other deps to latest:
- react/react-dom 19.2.4 → 19.2.6
- next-intl 4.8 → 4.11
- motion 12.35 → 12.38
- tailwind-merge 3.4 → 3.5
- geist 1.5 → 1.7
- @radix-ui/* unchanged (already latest within their ranges)
- @opennextjs/cloudflare 1.17 → 1.19.8
- @playwright/test 1.56 → 1.59
- @tailwindcss/postcss + tailwindcss 4.1 → 4.2.4
- @types/node 22 → 25.6
- @types/react 19 → 19.2.14
- eslint 9 → 10.3 (works because we now reference @next/eslint-plugin-next
  configs directly, not eslint-config-next)
- eslint-plugin-prettier 5.5.4 → 5.5.5
- globals 16 → 17.6
- postcss 8.5.6 → 8.5.14
- prettier 3.6.2 → 3.8.3 (no formatting changes detected by --check)
- prettier-plugin-tailwindcss 0.6 → 0.8
- typescript 5.9.3 → 6.0.3
- typescript-eslint 8.56 → 8.59
- wrangler 4.71 → 4.90

Verified locally:
- bun install --frozen-lockfile: 685 packages, no errors
- bun run format:check: pass (no diffs after `bun run format`)
- bun run lint: pass
- bun run type-check: pass (TypeScript 6 + @types/node 25)
- bun run build: pass (Next 16 build, 21 static pages, all 4 locales)
- bunx opennextjs-cloudflare build: pass (.open-next/worker.js produced)

Note: Next 16 `build` log relabels the Middleware row to "Proxy
(Middleware)" — purely cosmetic, no behavior change.
