chatgui: rlottie animated emoji with hover-to-animate, drag-to-select

Browse Source 
- Add LottieIcon class (TGS gzip decompress + rlottie C API render)
- Add AnimTimer singleton (33ms tick, activate/deactivate refcount)
- Add EmojiButton (hover-triggered animation in emoji picker)
- Add AnimatedEmoji support to EmojiData (5 TGS mappings)
- MessageDelegate: QTextLayout-based animated emoji overlay (text + reactions)
- ChatView: drag-to-select (click deselects, 5px drag starts selection)
- ChatView: hoveredIndexChanged signal for hover-triggered animations
- MessageList: wire AnimTimer tick to viewport update, hover → activate
- CMake: AUTORCC, rlottie, zlib dependencies
- Add 5 TGS animations as Qt resources
