Removed complex modal implementation and replaced with simple link to dedicated credentials page to eliminate all modal issues. Changes: - Add credentials action to TutorialsController - Remove layout false restriction for credentials - Replace button with simple link_to for Demo Credentials - Remove entire modal HTML structure - Remove all JavaScript for modal initialization - Remove fetch/AJAX complexity The credentials view already existed but was modal-only. Now it's a proper page that users can navigate to directly. Much simpler! 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
