Register the Kling 可灵AI 3.0 visible text mark; park Yuanbao and cat-logo (measured)

Kling (USCC cohort 91110108335469089C, n=30): kling_engine.py, gate 0.35
(clean p99 0.304 / max 0.320), strict-only, unimodal 0.12/short on the
shared ladder, fitted locate box, no rival margin (crossfire 1/400 doubao
below gate, 0 jimeng, 0 clean), parity 9/9 detect->fill->re-detect.
Suppresses the jimeng pill like doubao/qwen. identify gains visible_kling.

Yuanbao: measured negative -- the two-line italic block does not separate
from clean corners on either front-end at any render/box/font setting;
the fitted recipe stays in render_vendor_silhouettes.py MARK_OPTS.

cat-logo: cohort has only 2 unique carriers, parked on evidence; the
draw_catlogo silhouette already separates (0.50 vs clean max 0.333), so
registration is a gate pick once more uniques arrive.

vendor_mark_calibrate: --fit-geometry takes locate-box overrides (two-line
marks were clipped by the inherited box) and the aspect sweep reaches 0.62.
