v0.15.6: Authentication & Docker Flow Updates

This release focuses on clearer authentication and Docker credential flows, plus usability tweaks to topology and organization management.

Improvements

Refine Docker socket proxy messages for local targets and consolidate instructions into the credential wizard, making Docker-based scans easier to set up (#4022fee9, #24fd7b1b, #af0c571f).
Rework authentication flow with clearer OIDC error messages, selectable login methods, and improved last login tracking so users can easily sign in the way they expect (#445d18fb).
Improve visual feedback for test results, toast messages, navigation, and text wrapping for a smoother in-app experience (#84435c70, #5f8b25cf).

Guard against accidental deletion of your last topology, ensuring one always remains; the delete button is now only disabled when deletion isn't allowed (#02c66841, #4b386db1, #13a1a862).
Fix discovery and onboarding flow issues, resolving stalled scans and navigation bugs on first use (#762ec13c).
Fix organization deletion, allowing you to fully remove an org when needed (#a87fd267).
