Full Changelog

The image repository is /configs not /ui:
hub.friendly-tech.com/configs/ft-configs-ui

Fix BACKEND_URL examples to the host-only form (a path component breaks
nginx variable proxy_pass and the readiness probe). Remove RUNTIME_API_PATH
from the docs: entrypoint.sh writes a fixed /configs-service API path and
never reads that variable. Clarify the METRICS_ALLOW_IP default and
allow-list behaviour.

Rename docker-compose.yml to compose.yml and update doc references.

The GitHub Actions cache service can return transient 5xx/4xx HTML
errors that fail the whole build at the cache export step. Add
ignore-error=true so a cache-to failure no longer aborts the image
build and push.
