Pin explicit Compose project name

Without this, Compose derives the project name from the directory
basename — fine today, but a silent trap if this repo is ever checked
out under a differently-named sibling path/host and someone reuses
"top-tickets" elsewhere. Value matches the current derived name
exactly, so this is a no-op for the running deployment.
