Labor ward TOR 3.11 gap-fill: WHO partograph with alert/action lines, ICD frequent-code helper, obstetric high-risk projection

The ห้องคลอด (labor ward) module closes 34 requirements from TOR 3.11. Highlights: newborn registration, a command-center hub, and a WHO partograph that renders alert and action lines so deviations are visible in real time.

An obstetric high-risk projection trigger now writes carried-forward flags into encounter_journey_cache.clinical_flags and active_alerts before insert, so high-risk and ANC context follows the patient and surfaces as a fail-open worklist badge.

An ICD frequent-code helper speeds diagnosis entry, and the module adopts the modern container and linkage pattern shared across the inpatient suite.
