Subject: Add API key management UI and wire S2 key to MCP

- Settings modal on project list page for OpenAI, Anthropic, OpenRouter, Gemini, Semantic Scholar keys
- Keys stored in userData/api-keys.json, masked by default with show/hide toggle
- S2 API key passed to MCP server via .lattex-mcp.json to avoid rate limits
