fix(infra): resolve NestJS dist build and Prometheus target issues
NestJS: disable incremental in 6 services tsconfig.json to fix dist not emitted when nest-cli deleteOutDir conflicts with tsc tsbuildinfo. classes/iam: import HealthModule in AppModule to fix /healthz 404. classes: rewrite HealthController to Drizzle getDb from TypeORM DI. teacher-bff: add /metrics endpoint for Prometheus scraping. infra: add node/mysql/redis exporters to observability profile. mysql-exporter v0.15.1 uses command-line flags not DATA_SOURCE_NAME. prometheus: enable web.enable-lifecycle for hot reload.
