Subject: [PATCH] WordPress: set minRam floors so first-boot install doesn't
 OOM

Every app service runs `wp core install` at first boot (base initCommands,
gated by zsc execOnce). On the 0.125 GB platform default, that spike
(php-fpm ~113 MB + wp-cli ~90 MB) OOM-killed the init process, and
--retryUntilSuccessful turned it into a crash loop. verticalAutoscaling
reacts too slowly for a sub-second spike, so the floor must absorb it.

- AI Agent appdev + Remote (CDE) app: minRam 1 + maxContainers 1
  (dev workstations also run composer/wp-cli in-container over SSH; dev
  uses SSHFS so pin a single container).
- AI Agent appstage + Stage app: minRam 0.5 (install-spike only).
- HA Production app: minRam 0.5 under the existing cpuMode DEDICATED
  (0.5, not 1, to avoid wasting RAM across up to 6 dedicated containers;
  steady-state scales up from the floor).
- Small Production already had minRam 0.5; Local has no app service.
