ci(gitea): fix deploy path — docker-compose.yml moved to deploy/

The Start Docker stack and Deploy steps referenced docker-compose.yml at
the repo root, but the file moved to deploy/ as part of the deploy.sh
refactor. The cp commands failed with 'cannot stat docker-compose.yml'
and the deploy step aborted.

Updated both cp paths to deploy/docker-compose.yml. The cd $APP_DIR and
docker compose -f $APP_DIR/docker-compose.yml references are unchanged
because they point at the deployed copy in APP_DIR, not the repo.
