feat: redesign contracts page with left-tree right-detail layout

- Left sidebar: tree menu showing all contracts grouped by contract type
  and lifecycle status (each contract is a leaf node)
- Right panel: selected contract's detail including auto-review result,
  lifecycle status with transition buttons, generation quality
- "Generate New Contract" moved to Drawer with step-by-step wizard
- Modern card-based styling consistent with templates page
