Bump zigpy to 0.91.2 and migrate from enum_factory to native enum types

[Copilot]

• Update minimum zigpy version from 0.78.0 to 0.91.2 in pyproject.toml
• Migrate enum_factory imports to use enum40, enum24, enum64 directly from zigpy.types in zigpy_znp/types/basic.py
• Run test suite to verify all tests pass (389 tests passed)
• Verified enum serialization/deserialization works correctly
• Fix pre-commit configuration issues
  • Update flake8/pflake8 to version 7.0.0 for Python 3.12 compatibility
  • Fix flake8 C419 warnings (unnecessary list comprehensions in tests)
  • Update mypy to v1.19.1 and zigpy>=0.91.2 dependency
  • Fix all mypy type errors properly (no suppression of real issues)
    • Fixed write_devices return type annotation to None
    • Fixed method signatures for zigpy 0.91.2 API compatibility
    • Added property setters where needed
    • Fixed LVList type parameters: LVList[uint16_t, uint8_t] not LVList[uint8_t, uint16_t]
    • Fixed type annotations for better compatibility
• Run pre-commit run --all-files successfully - ALL CHECKS PASS!

Original prompt

Bump the minimum zigpy version to 0.91.2 and migrate enum_factory to the correct enum* type from zigpy. I believe it is enum40. Run pre-commit checks and the test suite to ensure all tests pass. Some tests may be flaky so run once or twice to get them to pass.

@copilot The zigpy_t.LVList changes are incorrect. zigpy_t.LVList[t.uint16_t] is zigpy_t.LVList[t.uint16_t, t.uint8_t], not zigpy_t.LVList[t.uint8_t, t.uint16_t].

@copilot The zigpy_t.LVList changes are incorrect. zigpy_t.LVList[t.uint16_t] is zigpy_t.LVList[t.uint16_t, t.uint8_t], not zigpy_t.LVList[t.uint8_t, t.uint16_t].

Fixed in commit 8ab32b4. Changed from LVList[uint8_t, uint16_t] to LVList[uint16_t, uint8_t] (item_type first, length_type second).
