feat(asl): Complete Tool 4 SR Chart Generator and Tool 5 Meta Analysis Engine

Tool 4 - SR Chart Generator:
- PRISMA 2020 flow diagram with Chinese/English toggle (SVG)
- Baseline characteristics table (Table 1)
- Dual data source: project pipeline API + Excel upload
- SVG/PNG export support
- Backend: ChartingService with Prisma aggregation
- Frontend: PrismaFlowDiagram, BaselineTable, DataSourceSelector

Tool 5 - Meta Analysis Engine:
- 3 data types: HR (metagen), dichotomous (metabin), continuous (metacont)
- Random and fixed effects models
- Multiple effect measures: HR / OR / RR
- Forest plot + funnel plot (base64 PNG from R)
- Heterogeneity statistics: I2, Q, p-value, Tau2
- Data input via Excel upload or project pipeline
- R Docker image updated with meta package (13 tools total)
- E2E test: 36/36 passed
- Key fix: exp() back-transformation for log-scale ratio measures

Also includes:
- IIT CRA Agent V3.0 routing and AI chat page integration
- Updated ASL module status guide (v2.3)
- Updated system status guide (v6.3)
- Updated R statistics engine guide (v1.4)

Tested: Frontend renders correctly, backend APIs functional, E2E tests passed
