refactor(db): port metrics storage + service domains to sqlc (#75)
First tranche of the ~300-site raw SQL port. Metrics: node/service/ instance rows via generated queries; aggregation moved off TimescaleDB's time_bucket onto portable date_bin (PG14+); interval uptime returns epoch seconds; per-container writes dropped (container_metrics FKs a different model — collector shape never matched). Domains: all reads/writes through sqlcdb including the create transaction via WithTx; default-domain and services.domain invariants unchanged. Both paths covered by live Postgres tests gated on METRICS_TEST_DSN. Generated with [Devin](https://devin.ai) Co-authored-by: Devin <158243242+devin-ai-integration[bot]@users.noreply.github.com>
