feat(tui): add paste shortcuts fallback to read raw image from clipboard

Browse Source 
Terminals like iTerm2 do not emit  for non-text clipboards. When
users press common paste keys (Ctrl+V, Ctrl+Shift+V, Shift+Insert), dispatch an
empty paste to the composer. The composer already treats empty paste as a cue to
attempt  via arboard+image and attach the PNG path.

This keeps normal text paste behavior (Cmd+V still triggers Event::Paste) and
adds a sensible fallback for image-only clipboards.

// Fallback: attempt clipboard image paste on common shortcuts.
// Many terminals (e.g., iTerm2) do not emit Event::Paste for raw-image
