[Ellipsis] [BUG] Zep Admin console leaks database password

[ellipsis-dev]

Summary:

⚠️ We couldn't build/test your project to verify our changes. Add a Dockerfile to significantly improve code quality.

Issue: #316

Implementation:

1. Update the regular expression in redactHTMLEncodeConfig
   • In the file /pkg/server/webhandlers/settings.go, locate the function redactHTMLEncodeConfig. Find the line with the regular expression (?i:postgres://[^:]+:)([^@]+). Replace this regular expression with (?i)(postgres://[^:]+:)([^@]+). This change moves the case-insensitive flag out of the first group, making it a capturing group and fixing the issue with the password not being redacted.
2. Test the updated regular expression
   • Use the Go playground link provided by the user to test the updated regular expression. Replace the regular expression in the Go playground with the updated one: (?i)(postgres://[^:]+:)([^@]+). Run the code and confirm that the password is correctly redacted from the DSN.

Report:
