feat(pipeline): firmware SBOM via tramiton reproducible build (phase 2)
Upgrade the firmware SBOM from analysis-only to a full reproducible build: run
tramiton's NixBackend (`seal_and_build`) over the ingested source to produce a
sealed lock whose libraries are pinned and whose firmware artifact carries a
content hash, then render the SBOM from the lock plus deep binary SCA of any
pre-compiled inputs — the complete bill of materials (toolchain + every fetched
library + the firmware image), mapped into `SbomEntry` rows.

Graceful by design: when no nix backend is available (or the build fails / times
out at 15m), it falls back to the analysis-only components (toolchain +
resolvable libraries), so a nix that can't run in the deployment never breaks a
scan.

Infra: the agent image now installs `nix-portable` (rootless, single binary;
best-effort — a failed download just leaves the analysis-only path). The nix
store lives under `NP_LOCATION=/data/compliance-scanner` — mount a PERSISTENT
volume there in the deployment, otherwise every firmware scan re-fetches
nixpkgs + cross toolchains.

Adds the `tramiton-sbom` dependency.
