Add account edit modal — package, PHP version, email

- New accounts/update endpoint: updates package_id, php_version, email,
  and notes; switches PHP-FPM pool when version changes
- Edit button on each account row opens pre-populated modal
- Modal shows email, package dropdown, PHP version selector; domain
  is read-only with tooltip explaining it can't change
