feat: auto-fill MCP server description with app description

Fix #22443: MCP server description now defaults to app description
- Backend: Make description optional in MCP server API, auto-use app description when empty
- Frontend: Support auto-filling app description in MCP server modal
- Allow creating MCP servers without explicit description
- Improve user experience by reducing required input fields

Changes:
- api/controllers/console/app/mcp_server.py: Make description optional, auto-fill with app description
- web/service/use-tools.ts: Make description optional in API types
- web/app/components/tools/mcp/mcp-server-modal.tsx: Support app description auto-fill
- web/app/components/tools/mcp/mcp-service-card.tsx: Pass app info to modal
