Update linter configs and enable CSS linting

Consolidate and tighten linting configuration: remove .eslintignore and .stylelintignore and move patterns into .eslintrc.json (ignorePatterns) and stylelint.config.mjs (ignoreFiles). Enable/enforce CSS linting in the super-linter workflow (add npm ci, set CSS_FILE_NAME, skip dependabot runs). Bump stylelint in package.json to 17.5.0. Add "svg" dictionary to cspell and enable additional htmlhint rules (button-type, frame-title, main-require, tag-no-obsolete).
