PR Summary

• Updates to Documentation
  The old bolt-pro.md document was deleted, and a new filament-bolt-pro.md document was added. The new document includes comprehensive information about the Zeus Bolt Pro plugin, its features, integration with the Advanced Tables plugin, supplementary images, and additional resources. An existing document, filament.md, was also updated to reflect the new link for Bolt Pro.

• Aesthetic Updates to Error Pages
  Changes were made to the color of SVG icons in three different error pages: date-not-available.blade.php, login-required.blade.php, and one-entry-per-user.blade.php. This enhances the user experience by ensuring visual consistency across all error pages.

• Visual Improvements to Filament Resource Pages
  The show-entry.blade.php page had the text color of its heading updated. This minor tweak improves readability and overall aesthetic appeal of this page.

• Theme Enhancement
  The visual appeal of the Zeus Bolt theme was enhanced by modifying color properties in fill-forms.blade.php, list-forms.blade.php, and show-entry.blade.php. Changes in background color and text color of various elements lead to an improved user interface and overall user experience.
