fix(ui): force Event Details modal z-index via inline style

Applies `z-index: 140` directly to the Event Details modal element via inline styles in JS to guarantee it renders above the Video Player (z-index 130), bypassing potential CSS specificity or build pipeline issues. This resolves the reported regression where the details modal remained obscured.
