feat(card): split provenance vs freshness — add generated_at liveness signal#2

… signal
The card's _meta["one.faf/context"].generated was request-time, silently
disagreeing with the deterministic `generated` in the .faf it points to —
on the one artifact whose thesis is "discovery and protocol agree, no drift."
Now two honest, clearly-named fields:
- generated: deterministic provenance, single-sourced from the served .faf
(FAF_GENERATED, parsed from project.faf) — card and artifact agree.
- generated_at: freshness/liveness (request time) — the declarable signal
floated in SEP-2127 (#2127). Provenance != freshness.
.faf artifact untouched (still deterministic, still Trophy). Parity test now
compares `generated` too. 39/39 pass.
