fix(images): card facts read the inspector's projected graphs

The inspector hands its browser parser only graphs the inspection
projection parsed (strict JSON, depth 64, node ceiling); a deeper record
is "limited" there, so the legacy fill never runs and no seed shows. The
card parsed the raw records instead and showed a seed the inspector did
not, e.g. for a 900-deep class_type beside a normal sampler.

project_graph() is now the one projection step, used by the inspection
response and by the card. The card runs the shared parser on the
projected graphs, the same values the browser receives: big integers
arrive as their exact digits, so the separate exact-integer re-parse and
the parse_js_json flag it needed are gone.
