refactor(deploy): simplify script to git push-based deployment

Replace the previous Next.js build + rsync + archive workflow with a
minimal `push_to_server` helper that only does `git push` to the
`server` remote. Build, install, and start are now expected to be
handled by the server's post-receive hook, removing duplicate logic
and shrinking the script from 164 lines to 46. The old `build`,
`deploy`, `archive`, `setup_env`, and `check_local_build_dir`
functions (along with pnpm/rsync/sshpass usage) have been removed.
