feat: clean up mobile remotion page — remove preview player and download button

Remove unused Player, ImageComposition, useMemo imports and all associated
computed values (combinedUrls, previewWordTimings, ENDING_FRAMES, totalFrames,
previewLogoUrl, previewStoreName, cloudinaryConfig query). Remove Aperçu card
with broken Player preview, download button, and conditional generate button wrapper.
