Add rich message bubble with inline media support (v1.5.0)

Features:
- Selectable text in all messages (fixes regression)
- Clickable links (auto-detected URLs with underline styling)
- Inline images/GIFs (jpg, png, gif, webp auto-displayed)
- YouTube embeds (shows thumbnail with play button overlay)
- Message parsing separates text from media content
- Uses Coil library for efficient image loading

Implementation:
- New RichMessageBubble component replaces ChatMessageBubble
- Parses message content into Text/Image/YouTube parts
- ClickableTextWithLinks handles URL detection and tap events
- ImageContent displays media with click-to-fullscreen
- YouTubeEmbed shows thumbnail and opens in YouTube app
- Added Coil dependencies (coil-compose + coil-gif)

Version: 1.5.0 (versionCode 41)
