feat: implement session-based architecture for OPRO

- Add session layer above runs to group related optimization tasks
- Sessions use first task description as name instead of 'Session 1'
- Simplified sidebar: show sessions without expansion
- Add '+ 新建任务' button in header to create runs within session
- Fix: reload sessions after creating new run
- Add debugging logs for candidate generation
- Backend: auto-update session name with first task description
