fix(imitation): skip pose lookup during collection

[ruthwikdasyam]

Contribution path

• Small, safe change that does not need a tracking issue

Problem

Imitation collection streams do not use stored spatial poses, but the memory2 recorder still attempted frame and TF lookups for every message. This produced repeated missing-pose warnings and unnecessary TF recording work.

Solution

• Skip pose resolution entirely for recorder streams configured as poseless.
• Mark imitation image, joint-state, and episode-status streams as poseless.
• Disable unused TF recording in both imitation collection blueprints.
• Add regression coverage for the recorder behavior and blueprint configuration.

How to Test

uv run pytest dimos/memory2/test_module.py dimos/imitation dimos/codebase_checks/test_blueprint_kwargs.py

Simulation smoke test: dimos --simulation run learning-collect-quest-xarm7
