matrix-user-verification-service: switch to modern community.docker docker_image modules

Replaces `community.docker.docker_image` with the modern
`docker_image_pull` and `docker_image_build` split modules. Drops the
`ansible_version` compatibility ladder and the now-redundant
`_container_image_force_pull` variable (the new pull module handles
registry refresh natively via `pull: always`). Also registers
`_container_image_build_result` so that a self-build rebuild correctly
triggers a service restart.
