Scrollable OCR panel and copy-text shortcut

The OCR panel overflowed its container on long recognized text; it now
clips, caps at 40% of the preview height, and scrolls. Ctrl+Shift+C copies
an entry's text content (OCR text or QR payload for images) as plain text,
and the QR/OCR panels get Copy chips.
