gramps-web: raise memory 384M -> 1024M (OOM proven during validation)

v25.6.0 could not stay up under the 384M limit. Live evidence from the demo box:

  [ERROR] Worker (pid:559) was sent SIGKILL! Perhaps out of memory?
  [ERROR] Worker (pid:556) was sent SIGKILL! Perhaps out of memory?

gunicorn kept booting replacement workers that were killed in turn, so the
container never reached healthy and Traefik returned 404. mem_limit in
.felhom.yml raised to match the compose limit; mem_request 100M -> 384M.

Campaign 7 catalog sweep.
