✨ start of supporting GraphQL

[rneswold]

This branch will be the new 1.x branch once we have the same support for the control system that 0.x has (minus the ACNET crap.)

The new code imports python_graphql_client but this package is NOT listed in pyproject.toml or setup.py dependencies.

Do we want to keep pushing on this PR. I feel like we've changed plans since this started. Technically @KitFieldhouse has been assigned this work by PIP-II.
I'm fine pushing on this, but I think we should make clear the goal and refine the approach a bit.
We've got new AI tools now 😁

Here's a summary from Qwen Coder Next:

Critical (Must Fix Before Merge)

1. Fix _convertItem and _convertReply method signatures - missing self/@staticmethod
2. Add python_graphql_client dependency to pyproject.toml
3. Add input validation for device specifications
4. Add GraphQL error handling before processing responses

High Priority (Should Fix)

5. Add all exports
6. Add endpoint configuration (environment variable)
7. Add JWT validation with proper error messages
8. Document auth requirements (how to get JWT)

Medium Priority (Should Consider)

9. Add retry logic for network failures
10. Implement or remove subscription client
11. Consider adding async wrapper for sync GraphQL calls
12. Add pagination support for future historical data queries

Lower Priority (Nice to Have)

13. Add logging for debugging
14. Add request/response timing metrics
15. Document device specification format (DRF subset)
