Replace generic labels with specific model names

Changes in legend:
- "Model A better than avg" → "RWKV better than avg"
- "Model A worse than avg" → "RWKV worse than avg"

Changes in tooltip:
- "Compression A" → "RWKV Compression Rate"
- "Compression B" → "Qwen Compression Rate"
- "Model A Top10" → "RWKV Top10"
- "Model B Top10" → "Qwen Top10"

This makes the UI more intuitive by using actual model names
instead of generic Model A/B labels throughout.
