feat: enhance bottom drawer with expandable display and no auto-dismiss

Major improvements to the bottom drawer user experience:

🎯 **Compact Minimized Display**
- Shows all available data points in a single line with bullet separators
- Includes: Pokemon name, dex number, CP, level, HP, IV percentage, gender, processing time
- Fits in 80dp collapsed height for minimal screen real estate usage
- Clean status icon and dismiss button always visible

🔧 **Expandable Details View**
- Pull up or tap to expand to 240dp height showing full details
- Organized detail rows with labels and values
- Individual stats breakdown (Attack, Defense, Stamina)
- Technical info (processing time, timestamp, detection count)
- Smooth fade animations for expand/collapse transitions

🎮 **Enhanced Gesture Handling**
- **Tap**: Toggle between collapsed and expanded states
- **Swipe Up**: Expand drawer to show full details
- **Swipe Down**: Collapse expanded drawer or dismiss entirely
- **Smart thresholds**: Different swipe distances for expand vs dismiss
- No auto-dismiss - stays until manually dismissed

🎨 **Improved Visual Design**
- Compact data row with ellipsis for long content
- Structured detail rows with consistent spacing
- Better use of space with proper text sizing
- Maintains Material Design principles

Technical improvements:
- Dynamic window height adjustment based on state
- Proper cleanup of expanded/collapsed state
- Thread-safe state management
- Optimized layout updates and animations
