fix: resolve CI warnings (Node.js 20 deprecation + ESLint formatting)

Force Node.js 24 in all GitHub Actions workflows to suppress the
upcoming Node.js 20 deprecation warnings. Disable vue/html-indent and
vue/html-closing-bracket-newline ESLint rules that conflict with
Prettier formatting.

Closes #122
