Implement tenant isolation for Entries Service: switch transaction handling to tenantTransaction, introduce Flyway-based migrations for tenant schemas, and add JdbcTenantRegistry with control schema support. Include migration tests, schema initializations, and E2E tenant isolation. Update configuration and roadmap with completed A-1 tasks.
