fix(record): pass rename_map to make_policy in lerobot-record (#3240)

* fix(record): pass rename_map to make_policy in lerobot-record

Fixes #3181. The rename_map from dataset config was used for preprocessor
construction but not passed to make_policy(), causing feature mismatch
errors when camera key names differ between dataset and model config.

make_policy() already accepts a rename_map parameter and uses it to skip
visual feature consistency validation when remapping is active, but
lerobot_record.py was not passing it through.

* style: fix ruff format for ternary expression
