Bring codebase into compliance with bible contracts (A–E)

A (hardware-ingest-json v2.8-2.9): remove sensor location fields from schema
and collector; tag HardwareMemory.Location as json:"-"; add PlatformConfig to
HardwareSnapshot.

B (no-hardcoded-vendors): consolidate PCI vendor IDs into collector/pci_vendors.go;
replace all vendor-name string checks in isGPUDevice, isNVIDIADevice, isMellanoxDevice,
isAMDGPUDevice, matchesGPUVendor (sat_overlay), and validateIsVendorGPU (page_validate)
with numeric vendor_id comparisons.

C (module-structure): split app/app.go (1413 lines) into app.go + app_format.go,
app_network.go, app_services.go, app_packs.go, app_install.go — no logic changes.

D (go-code-style): wrap bare return err in interfaceAdminState and
interfaceIPv4Addrs (platform/network.go) with fmt.Errorf context including
the interface name.

E (go-project-bible): add bible-local/architecture/data-model.md and
bible-local/architecture/api-surface.md.
