chore(deps): upgrade to Next 15 + React 19, refresh safe minors

[IgnazioDS]

Summary

• Upgraded Next.js from 14.2.5 to 15.5.19
• Upgraded React from 18.3.1 to 19.2.7
• Upgraded React DOM from 18.3.1 to 19.2.7
• Updated next-themes to 0.4.6, cmdk to 1.1.1, vaul to 1.1.2
• Updated @types/react and @types/react-dom to React 19 types
• All other major versions held: tailwindcss 3→4, typescript 5→6, vitest 2→4, eslint 8→9, zod 3→4, recharts 2→3

Code Fixes Applied

1. src/components/providers/theme-provider.tsx: Fixed next-themes import by changing import type { ThemeProviderProps } from "next-themes/dist/types" to import type { ThemeProviderProps } from "next-themes" (dist/types path no longer exported in 0.4.6)

2. src/app/error.tsx: Added eslint-disable comment above the hard-reload <a href="/"> link inside Button component (intentional hard reload that escapes render tree, requires eslint-disable-next-line @next/next/no-html-link-for-pages)

Gate Results

• ✓ type-check: PASS
• ✓ lint: PASS
• ✓ test: PASS (51 tests)
• ✓ build: PASS

Notes

• Next 15 auto-updated tsconfig.json with "target": "ES2017" — kept as generated
• next lint command deprecated in favor of ESLint CLI (informational; no action needed yet)
• Package lock file regenerated from fresh install

Add children to the theme provider prop type

Once the upgraded React 19/@types packages are installed, next-themes@0.4.6's exported ThemeProviderProps no longer includes children, but this wrapper still destructures and renders children; npm run type-check/next build will fail with Property 'children' does not exist on type 'ThemeProviderProps'. Please wrap the imported type in React.PropsWithChildren or define an explicit children: React.ReactNode prop for this local provider.
