feat(ui): add download image button to duel view

[KrishnaX12]

DESCRPTION !!

What does this PR do?

Adds a "Download" button to the Rivalry (Duel) view so users can save and share their 1v1 matchups as high-quality posters.

Implementation details

• Integrates html-to-image via the existing renderCardImage utility to capture the Duel view.
• Applies custom capture hooks to automatically exclude navigation elements (top bar and footer) from the downloaded image.
• Adjusts the duel's minHeight and adds symmetric padding during capture to export a pristine, tightly-cropped poster.
• Redesigned the share/download action buttons into a sleek, uniform grid using a flex-col layout, preventing awkward text wrapping and matching the premium feel of the rest of the app.

Hey @Younesfdj, I've added the Download button for the Duel view. Could you please take a look when you have a moment? Thanks!

Potential browser compatibility issue: ClipboardItem and navigator.clipboard.write() may not be supported in all browsers. Could we add a capability check and provide a fallback (such as downloading the image or copying the duel link) when image clipboard support isn't available? This would prevent the "Copy image" action from failing silently.

@sheikhwasimuddin

Thanks for pointing this out, @sheikhwasimuddin. I’ve added a capability check for image clipboard support and implemented a download fallback for unsupported browsers. I’ve
also attached a video demonstrating the updated behavior. Could you please review it again when you have a chance? and if u want me to remove copy clipboard option jus tell me

fixed clipboard stuff

[sheikhwasimuddin]

Re-checked the latest changes. The clipboard capability check and download fallback address the compatibility concern I raised earlier. The implementation looks good from my side. ✅

Approved.
