Add objective integration tests for all example_ws configs

[rlpratt12]

Summary

• Add objectives_integration_test.py to 11 config packages (kitchen_sim, april_tag_sim, grinding_sim, dual_arm_sim, factory_sim, hangar_sim, kinova_sim, space_satellite_sim, space_satellite_sim_camera_cal, mock_sim, multi_arm_sim)
• Each test auto-discovers objectives via SystemConfigParser and runs them with per-config skip lists for user-input/ML/GPU objectives
• New objectives are automatically tested — if one requires skipping, CI fails and the PR author adds it to the skip list (fail-safe design)
• Add CI matrix job to run each config's tests in parallel via the existing workspace_integration_test reusable workflow
• Add missing ament_cmake_pytest + moveit_pro_test_utils test deps across all configs (including existing lab_sim)

Known TODOs

• Skip lists are best-guess based on objective names/XML analysis — need to validate with actual CI runs
• The existing integration-test-in-studio-container job still runs all tests including these, causing double-runs. Consider adding --packages-skip for config packages to that job
• 600s timeout may need tuning for configs with many objectives (e.g. lab_sim has 80)
• Cancel objectives sets are empty for new configs — looping objectives may need to be identified and added

Test plan

• All 12 test files parse correctly with valid Python syntax
• Skip list objective IDs verified against actual main_tree_to_execute XML attributes — all match
• CMakeLists.txt and package.xml changes follow existing lab_sim pattern
• Run integration tests for mock_sim (simplest, no skips) to validate end-to-end
• Run integration tests for a config with skips (e.g. kitchen_sim) to validate skip behavior
