feat(sprint-1): CannaManage foundation — compliance engine, JPA entities, tests TC-001→TC-025

- Maven multi-module project (parent + domain + service + api)
- AbstractTenantEntity with Hibernate @Filter for multi-tenancy (explicit getters/setters, Java 25 compatible)
- TenantContext ThreadLocal for request-scoped tenant isolation
- 8 JPA entities: Club, Member, Strain, Batch, Distribution, MonthlyQuota, StockMovement, User
- ComplianceConstants with CanG §19 limits (25g/day adult, 50g/month adult, 30g/month under-21, 10% THC cap)
- ComplianceService: checkDistributionAllowed() with fail-fast sequential CanG checks
- Unit tests TC-001→TC-025: 25/25 passing, 100% line+branch coverage on ComplianceService (JaCoCo 0.8.13)
- Flyway V1__initial_schema.sql: all 8 tables + indexes
- docker-compose.yml: PostgreSQL 16 local dev
- application-local.properties: local profile configuration
