🎨 Palette: List View UX & Accessibility Enhancements

[Woschj]

💡 What: This PR introduces several micro-UX and accessibility improvements to the application's list views.

• Search Experience: Added a "Clear Search" (X) button to the search input and converted the layout to use DaisyUI join for better visual grouping.
• Visual Feedback: Implemented a "No Results Found" state that appears when filters or search terms return no matches.
• Unified Filtering: Refactored the JavaScript filtering logic into a central, robust function that automatically handles all page-specific filters (category, location, status) based on data attributes.
• Table Accessibility: Enhanced sorting headers with role="button", tabindex="0", and keyboard support (Enter/Space), along with clear focus indicators.
• HTML Integrity: Fixed a mismatched div/button tag for the QuickScan trigger in the base template.

🎯 Why: To improve the overall usability and accessibility of the core inventory management screens, making them more intuitive for all users.

♿ Accessibility:

• Native button for QuickScan trigger.
• Keyboard-accessible table sorting.
• Descriptve ARIA labels for interactive elements.
• Improved focus visible states.
