Arcane: write both env names, stop shipping the unused .env

The compose file from main now uses ARCANE_ENCRYPTION_KEY and
ARCANE_PROJECTS_DIRECTORY, which the latest image (2.17.3) does not read,
so it panicked on a missing ENCRYPTION_KEY. Arcane 3 in turn refuses to
start when only the old names are set. Install and update now keep both
names in compose.yaml, which also carries existing installs over to 3.

The .env was never referenced by the compose file, but compose parses it,
and the unanchored ENCRYPTION_KEY sed turned the renamed line into
ARCANE_#ENCRYPTION_KEY and broke every install. New installs no longer
download it; update repairs the broken line.
