Add generalized robot calibration and monitoring

[temiroff]

What changed

• adds generalized calibration-control and mock provider contracts
• adds compute-device and ROS capability discovery nodes and templates
• improves Robot, RobotJointDefinition, RobotMonitor, and RobotServo profile and diagnostic behavior
• keeps profiles, calibration, limits, and hardware identity visible and editable

Why

Robot setup, calibration, monitoring, and capability discovery need stable provider-neutral contracts that work with local hardware and mocks.

Validation

• 129 robot tests passed (2 skipped)
• diff and credential-pattern checks passed

Physical robot motion was not exercised by automation.
