User accidentally released a feature flag to 100% of users due to a misconfigured release condition. The system should provide a clear, loud warning before saving a configuration that releases a flag to everyone.
### Feature request ## Is your feature request related to a problem? I mistakenly released my feature flag to everyone after playing with release conditions interface. I meant to add an internal cohort group as a target audience, but something went wrong and I didn't add the filter. Then I saved the configuration... which released the flag to everyone, since one of the conditions I ended up with was "100% of all users". It wasn't very well visible in the post-save flag overview, the difference was very minimal. | What I wanted | What I got | | ------------- | ---------- | | <img width="1200" alt="Image" src="https://github.com/user-attachments/assets/6ad088d0-e34b-40c5-9dbb-f9db7e0e63d0" /> | <img width="1200" alt="Image" src="https://github.com/user-attachments/assets/4f1312a6-010c-4982-abe7-898d30209266" /> | It's all on me, but PostHog UI could help better with my choices. ## Describe the solution you'd like A confirmation popup showing the effective percentage of all users t
