feat(zed): export depth at neural optimal resolution

Browse Source 
Restrict ZED depth export to neural modes and default offline MCAP conversion to the SDK-selected optimal depth size instead of camera resolution.

Add a configurable --depth-size option, propagate the actual returned depth dimensions into DepthMap metadata, and emit a dedicated depth calibration topic when depth resolution differs from video.

Update the batch and recording helper scripts to use the new neural-only depth mode surface and pass through depth sizing.

Verification:
- cmake --build build --target zed_svo_to_mcap mcap_multi_record_tester mcap_pose_record_tester -j4
- build/bin/mcap_multi_record_tester
- build/bin/mcap_pose_record_tester
