Fixes camera fast path logic and GPU buffer in dexsuite

[kellyguo11]

Description

Fixes a bad merge of the camera class logic to check for when to enable the fast paths.

Also fixes GPU buffer size that now needs to be increased for dexsuite environments.

Fixes IMU tests and URDF converter logic.

Fixes teleop tests where patching wasn't working correctly with the new lazy export mechanism.

Switches Factory and Forge environments to use timestamp logging to avoid overwriting the same folder when running multiple training runs.

Removes omni.kit.pip_archive from our app files to avoid any version conflicts between our and Kit's python dependencies.

Greptile Summary

Fixed camera fast path logic by replacing restrictive allowlist check with simpler RGB/RGBA detection. The new approach correctly enables the fast rendering path whenever full color rendering is not needed, supporting more data type combinations like depth + normals or depth + segmentation.

• Replaced allowlist-based logic (checking if all types in {depth, albedo, distance_to_*}) with direct RGB/RGBA check
• Added GPU buffer capacity overrides for dexsuite environments (gpu_found_lost_aggregate_pairs_capacity=2**29, gpu_total_aggregate_pairs_capacity=2**25)

Confidence Score: 5/5

• This PR is safe to merge with no concerns
• Both changes are straightforward bug fixes. The camera logic simplification makes the code cleaner and more correct, enabling fast path for more valid scenarios. The GPU buffer increases address capacity issues in dexsuite environments, following patterns used in other complex manipulation tasks.
• No files require special attention
