Store the standard V1/V2 preview cameras in their presets so the default display launch can use the shared bimanual.rviz configuration for both single-arm and bimanual models.

Changes

• Add preview.view.eye/lookat to the 11 existing V1/V2 presets.
• Preserve the former single-arm camera for single-arm variants, including gripper variants, and the former bimanual camera for the two default bimanual presets.
• Keep arm_only.rviz available for existing tutorial commands. The default rviz_config remains bimanual.rviz.

This PR is based directly on main and is independent of #131. Cell's own view remains in #131. Joint positions and model configuration are unchanged.

Validation

• All 33 existing ROS 2 Jazzy tests pass; no tests added.
• All 11 views convert back to the previous RViz Orbit parameters within 1e-7 (yaw compared modulo 2 pi).
• Parsed preset contents are unchanged apart from the new preview field. No RViz files, launch code or development documentation changed.
