De-flake CI

…tle/drift)

Both isaacgym single-gpu failures Kevin hit on #185 are marginal settle/drift
flakes in the behavior/camera suite, not regressions (each run failed a
different single test on the same commit; neither is in #185's diff, which only
reroutes OBJ-terrain env origins — a no-op for the procedural terrain these
tests use). This removes them at the source.

camera-orientation: the pin set only the root pose, then settled ~0.05s before
capture. The robot is un-actuated, so its joints sag during the settle, yawing
the pelvis-mounted camera enough to shift the off-axis panel across the vertical
centerline — a near-boundary env images TOP-LEFT instead of the expected
TOP-RIGHT. Adopt the same drift-hold the geometry/follow harnesses already use
(#175/#187): capture the spawn DOF pose, re-pin root + hold joints rigid +
zero velocities with a read-back-verify retry, and step a few frames before
render so the corrected pose reaches the frame.

static-support: a fixed 1.5s settle isn't always enough for every env's dropped
box to damp out its bounce, so a random box reads a few mm outside the tight 8mm
z-band (env0 fine at 0.402, another env marginally off). Settle-to-rest instead:
step in 0.25s chunks until every box's z is stable between chunks and its
velocity is ~0, capped at 4s so a genuinely unsupported box still falls through
and fails the assertion. The pass criteria (8mm band, over-post, post-fixed) are
unchanged.

Based on Kevin's #185 branch so it merges straight back into it.
