chore(deps): upgrade digiid-ts to 4.0.0 and update deps to latest stable

- digiid-ts 3.0.3 -> 4.0.0 (public API unchanged; requires Node >=22.12.0)
- Raise engines.node and .nvmrc to Node 22; update README prerequisite
- Bump vitest/@vitest/coverage-v8 to 5, jsdom to 30, dotenv to 18,
  vite to 8.3, eslint to 10.12, react to 19.3, and other dev tooling
- Hold TypeScript at 6.0.3 (typescript-eslint caps at <6.1.0)
- Refresh overrides with patched transitive deps, dropping stale pins
- Reformat utils.ts to satisfy prettier 3.9

Remaining audit finding (braces via nodemon/chokidar) has no upstream fix.
