fix: improve empty space utilization below upload box with keyboard s…

[matheusmurkdock]

Description

Fixed the empty space utilization issue below the upload box by replacing the generic "Upload a video to get started" text with a useful keyboard shortcuts panel. Also reduced the DropZone padding from py-12 to py-8 for a more compact layout.

Changes:

• src/components/FileUpload.tsx: Reduced DropZone vertical padding
• src/components/VideoEditor.tsx: Added keyboard shortcuts panel (Ctrl+O, Space, M, Esc)
• removed the redundant and repeated line of supported formats
  This makes the empty space functional by helping users discover keyboard shortcuts while maintaining a minimalist design aesthetic.
