Improve build/install scripts for multiple apps

Switch development builds to production and harden install/update steps across several apps.

- Akaunting: use `npm run production` instead of `npm run dev` in both install and update scripts to produce production assets.

- Blinko: make bun installs run with `--unsafe-perm`, run `bun run build:web` and `bun run build:seed`, copy built public assets into `/opt/blinko/server/public`, run prisma migrations, and execute the generated seed script. Add PORT and NEXT_PUBLIC_BASE_URL to the .env. Update the systemd service to use WorkingDirectory `/opt/blinko/server` and start the app with `node /opt/blinko/dist/index.js`.

- InvoiceShelf & SolidTime: stop capturing APP_KEY via `php artisan key:generate --show` + sed; instead run `php artisan key:generate` during install after composer install. SolidTime also runs `php artisan storage:link` after build. These changes simplify key generation and ensure proper storage linking.

Overall these updates ensure production-ready builds, proper artifact placement, and correct runtime configuration for services.
