fix(build): unbreak Railway deploy — ESLint no longer gates prod build

My earlier 'globals' devDep addition made eslint.config.js load
successfully during 'next build', which then surfaced a pre-existing
ESLint *error* and failed the build (commit b4d75ae deploy FAILED), so
prod was stuck on old code while the SMS-pumping abuse continued.

- next.config.js: eslint.ignoreDuringBuilds=true so lint (a dev/CI
  concern) can never fail the production build again.
- pwa-diagnostics.js: fix the actual syntax error — a botched global
  find/replace had turned the word 'browser' into the expression
  '(typeof window !== "undefined")' throughout this (unused) file,
  producing invalid object keys/property access. Reversed it; node
  --check + full 'next build' now pass.
