feat(assessments): layered clinical assessment engine end-to-end

Add a template-driven assessment system with universal intake, clinical
pathways, disease instruments (stroke MVP + extended, diabetes, and ten
specialty packs), scoring, patient outcome trends, REST/API + FHIR
export, and Enterprise org-level assessment analytics. Seed packs and
design/licensing docs ship for deploy and pre-GA review.

+### Clinical assessment content packs
+
+After migrate (and on each release that adds packs under `database/data/assessments/`):
+
+```bash
+cd /var/www/ladill-care/current
+php artisan db:seed --class=Database\\Seeders\\AssessmentTemplateSeeder --force
+php artisan db:seed --class=Database\\Seeders\\ClinicalPathwaySeeder --force
+# or full: php artisan db:seed --force
+```
+
+Packs are platform-global (no per-tenant copy). Enable the engine per organization via
+`settings.rollout.assessments_engine = true` (see design doc / `CareFeatures`).
+Pathway content lives under `database/data/pathways/`; assessment instruments under
+`database/data/assessments/`.
