Add biome + rolldown + lightningcss build pipeline for JS/CSS bundling & minification

- package.json with biome, rolldown, lightningcss devDependencies  
- biome.json: add CSS formatter support
- scripts/build-css.mjs: lightningcss resolves @import chain, bundles/minifies CSS  
- scripts/build-js.mjs: rolldown per-entry JS bundling (no code splitting)
- scripts/build.mjs: orchestrator for both CSS + JS
- scripts/check-build.mjs: staleness checker for CI/deploy guard
- justfile: add build, build-css, build-js, build-install, build-check recipes
- justfile: deploy recipe now runs build before deploy-code
- head.php + form-page.php: use dist/base.min.css instead of style.css
- All controllers + FormBootstrap: reference dist/*.min.{css,js}
- admin footer: load admin.min.js for all admin pages
- repertoire: use public.min.js instead of individual app JS files
- Fix stray '}' syntax error in admin.css line 305
- .gitignore: add app/public/assets/dist/
