Marc-André BombeckandClaude Opus 4.7 5d1ece1fd5 feat(db): HostMetric model for host-load sampling ...

Adds the per-minute snapshot table that backs the new admin host-load
chart above /admin/system-status. One row per minute, captured by the
pg-boss sampler in the next commit, with 7-day retention enforced
inside the worker so the table stays under a few thousand rows.

Schema mirrors what the chart needs:
  - load_avg_1/5/15 (DOUBLE PRECISION) — os.loadavg() output
  - mem_used_bytes / mem_total_bytes — derived from os.totalmem() and
    os.freemem(), kept as raw bytes so the API can compute either a
    percent or a MiB delta downstream
  - disk_read_bytes / disk_write_bytes — nullable cumulative byte
    counters from /proc/diskstats. NULL on macOS/Windows dev hosts;
    Linux production picks them up automatically. The API endpoint
    converts deltas to bytes-per-second between samples

Indexed by captured_at so the "last 2 hours" query stays index-only.

Migration 0032_host_metric. integration setup.ts adds host_metrics to
the truncate list so testcontainers stays clean across runs.
