fix(frontend): align project types with backend enums

- Fix ProjectStatus: use 'active' instead of 'in_progress'
- Fix AgentStatus: remove 'active'/'pending'/'error', add 'waiting'
- Fix SprintStatus: add 'in_review'
- Rename IssueSummary to IssueCountSummary
- Update all components to use correct enum values
