Docker, Docker-AIO: private registry, data volumes set from .env

Images now default to the registry 10.2.1.10:5500/admin instead of
ghcr.io/dariuszjaniak, in the compose files, the .env examples and the
READMEs.

Each data volume's source comes from .env: WARP_DATA_VOLUME,
WARP_POSTGRES_VOLUME, SEAWEED_DATA_VOLUME and SEAWEED_ADMIN_VOLUME.
Empty keeps the named volume; a host path bind-mounts that directory,
which must be writable by UID 10001 where the homeserver or the AIO
container uses it. Each .env example lists the ones its compose file
mounts.
