chore(quality): type-check and lint gates in pre-deploy, clean lint/tsc

- pre-deploy suite now runs tsc --noEmit and eslint; any failure aborts
  the release
- fix all TypeScript errors (FooterConfig.copyright removed after the CMS
  move; test guards/casts)
- fix all ESLint errors: <a>→<Link> and <img>→<Image> in Header/Footer,
  remove unused imports and explicit any in src
- eslint config relaxes no-explicit-any/no-require-imports/no-unused-vars
  for test and CommonJS config files (legitimate usage)

Closes MITHOME-81
