feat: unified model selector below mode toggle

- Model dropdown below mode switch applies to active agents
- In work mode: changes model for Rex/Maddy/Coder/Research + subagents
- In lab mode: changes model for Eric
- /api/apply-model endpoint: swap model + VRAM in current mode
- /api/switch accepts optional model param
- Removed separate lab model card (consolidated into one selector)
