Describe the Bug

Since switching to Blueprints with Docker labels for configuration, I encounter an issue when creating a rule for a region. The value parsing fails with the following error:

WARN: 2026/05/12 18:23:36 Blueprint application failed: Failed to apply blueprint from config: Error: Validation error: Invalid input: expected string, received number at "public-resources.my-app.rules[0].value"

Docker labels used:

pangolin.public-resources.my-app.name=My App
pangolin.public-resources.my-app.full-domain=my-app.example.org
pangolin.public-resources.my-app.protocol=http
pangolin.public-resources.my-app.targets[0].method=http
pangolin.public-resources.my-app.targets[0].hostname=my-app
pangolin.public-resources.my-app.targets[0].port=8080
pangolin.public-resources.my-app.targets[0].healthcheck.path=/
pangolin.public-resources.my-app.targets[0].healthcheck.hostname=my-app
pangolin.public-resources.my-app.targets[0].healthcheck.port=8080
pangolin.public-resources.my-app.targets[0].healthcheck.unhealthy-threshold=3
pangolin.public-resources.my-app.auth.sso-enabled=true
pangolin.public-resources.my-app.auth.sso-roles[0]=Member
pangolin.public-resources.my-app.rules[0].action=pass
pangolin.public-resources.my-app.rules[0].match=region
pangolin.public-resources.my-app.rules[0].value=150

When setting the value to a string (pangolin.public-resources.my-app.rules[0].value="150"), the blueprint application fails with the following error:

WARN: 2026/05/12 18:23:59 Blueprint application failed: Failed to apply blueprint from config: Error: Validation error: Value must be a valid UN M.49 region or subregion ID when match is 'region' at "public-resources.my-app.rules[0].value"

Environment

OS Type & Version: (e.g., Ubuntu 22.04) Debian 13
Pangolin Version: 1.18.4
Gerbil Version: 1.4.0
Traefik Version: 3.7.1
Newt Version: 1.12.5
Olm Version: (if applicable)

To Reproduce

Create a docker compose service with rule container labels:
- pangolin.public-resources.my-app.rules[0].action=pass
- pangolin.public-resources.my-app.rules[0].match=region
- pangolin.public-resources.my-app.rules[0].value=150
The blueprint application fails.

Expected Behavior

I can use region values for blueprint rules as docker container labels.
