pc: PC setup tracker at /trackers/pc on the hardware schema

- model the existing hardware schema in Drizzle (devices, components, new sensitivities)
- idempotent reconciling migration: new columns, checks, setup_overview view, grants, meta.tables
- seed: main PC labels/hostnames, planned AMD X3D + RTX 5090 build, stan-ovh (OVH RISE-S),
  other devices, sensitivity placeholders (no invented cm/360)
- owner-only add/edit via modals; public view hides notes/order numbers
- trackers dropdown entry + icon, seo/title/sitemap, owner write prefix
