Holding this bump — not merging yet, and deliberately leaving it open (closing would make Renovate stop re-proposing TypeScript 7).

Why: TypeScript 7.0.2 is now GA, but the current failure is not just the stale lock file. Regenerating frontend/package-lock.json against typescript@^7.0.0 locally resolves cleanly but produces 8 ERESOLVE peer-dependency overrides, and the type-check gate then crashes hard:

$ npm run check   # svelte-check
TypeError: Cannot read properties of undefined (reading 'useCaseSensitiveFileNames')
    at new FileMap (node_modules/svelte-check/dist/src/index.js:9013:72)

TypeScript 7 is the native (Go-port) compiler and changed the typescript.sys CommonJS surface that svelte-check@4.6.0 (and likely @typescript-eslint@8) rely on. Our toolchain does not support TS7 yet.

Revisit when svelte-check and @typescript-eslint ship TS7 support (watch their release notes). At that point this PR can be rebased/regenerated and merged.
