Describe the Bug

Summary

After applying a blueprint configuration via the Pangolin dashboard, resources return "Bad Gateway" until the target is manually deactivated and reactivated.

Steps to Reproduce

Open Pangolin dashboard and navigate to Settings > Blueprints
Paste blueprint configuration (example below)
Click Apply
Access the service URL (e.g., https://metube.example.com)
Result: "Bad Gateway" error

Workaround

Open Pangolin dashboard
Navigate to the affected resource (e.g., MeTube)
Go to Targets section
Disable the target entry
Click Save (may need to click multiple times for it to register)
Re-enable the target entry
Click Save again (may need to click multiple times)
Access the service URL
Result: Service works correctly

Example Blueprint

public-resources:
  metube:
    name: MeTube
    protocol: http
    full-domain: metube.example.com
    ssl: true
    auth:
      sso-enabled: true
      sso-roles:
        - Family
    targets:
      - site: your-site-identifier
        hostname: 10.96.0.152
        port: 8081
        method: http

Additional Notes

Reproducible issue - occurred at least 5 times across different services
Toggle workaround consistently resolves the issue for me

Environment

OS Type & Version: Debian GNU/Linux 13 (trixie)
Pangolin Version: 1.14.1
Gerbil Version: 1.3.0
Traefik Version: 3.6.4
Newt Version: 1.5.0

To Reproduce

Open Pangolin dashboard and navigate to Settings > Blueprints
Paste blueprint configuration (example below)
Click Apply
Access the service URL (e.g., https://metube.example.com)
Result: "Bad Gateway" error

Expected Behavior

After applying a blueprint via the dashboard, targets should be immediately active and functional without manual intervention.
