fix(compose): preserve named-volume access mode when adding suffix

The randomize/isolated-deployment volume transform split mount strings
on ':' and kept only the first two segments, so an access mode like
:ro, :z or :Z was silently dropped and read-only mounts became
read-write. Keep the full path+mode remainder when rebuilding the
mount string.

Fixes #4818
