Add card MCP tools integration and fix ServiceClient methods

### MCP Server Enhancement:
- Add 3 new card-related MCP tools: get_user_cards, draw_card, get_draw_status
- Fix ServiceClient missing methods for ai.card API integration
- Total MCP tools now: 20 (including card functionality)

### ServiceClient Fixes:
- Add get_user_cards() method for card collection retrieval
- Add draw_card() method for gacha functionality
- Fix JSON Value handling in card count display

### Integration Success:
- ai.gpt MCP server successfully starts with all 20 tools
- HTTP endpoints properly handle card-related requests
- Ready for ai.card server connection on port 8000
