The propresenter parser package was renamed; it is consumed as bussnet/propresenter7-php-api (dev-master) from the forgejo VCS repo. Update the stale propresenter/parser references in the local-dev toggle and docs so the local path-repo toggle keeps working.
Parser master was renamed (propresenter/parser -> bussnet/propresenter7-php-api),
so 'composer update propresenter/parser' fails to re-resolve dev-master. Pin the
parser solely via the committed composer.lock; Dockerfile 'composer install'
deploys the locked ref and the lock COPY busts the build cache on change.
