fix(ui): remove display:none from #playerModal selector to fix modal visibility

The #playerModal ID selector in `css/tailwind.source.css` incorrectly set `display: none`. This ID selector has higher specificity than the `.hidden` utility class (applied by Tailwind) used by `VideoModal.js` to toggle visibility.

When `VideoModal.js` removed the `.hidden` class to show the modal, the ID selector's `display: none` remained active, keeping the modal hidden.

Also removed the `#playerModal.flex` rule as `.bv-modal` already provides flex behavior.

This fixes the issue where clicking a video card would trigger the logic but fail to display the player.
