v2.4 — Auto-Import & UX Polish

Drop a file or click the zone → cookies import instantly, no extra button click required
Drag anywhere on the Import panel (not just the small box) to trigger import
Paste area hidden by default to reduce scrolling — tap "Paste manually" to expand
Popup layout fits in 440×600 without scrolling
Fixed: browsing a file in popup mode now correctly opens a tab and auto-fires the file dialog
