Portainer's git-stack checkout does not materialize sibling repo files
at the relative bind path, so ./serve-roms.json mounted as an empty
auto-created directory and tailscale serve failed ('is a directory').
Switch to an absolute /config/share/serve-roms.json bind (matching every
other stack's /config convention); the file is mirrored on the host.
