fix: swipe stays open for button tap, loading skeleton for chats

- Swipe left now snaps open and action buttons are tappable (onClick)
- Swipe right still executes pin immediately on release
- chatsLoading state in store: shows skeleton animation while loading
- "Нет чатов" only shown after chats have finished loading
