chore: Split up test_containers.py into data subdirectories

[allenporter]

Split up the existing containers test into tests for the protocol specific subdirectories, following the newr roborock.data module structure.

This also updates all mock_data references to reference the tests path rather than a relative path.

Pull request overview

This PR reorganizes the test suite by splitting the monolithic tests/test_containers.py file into protocol-specific subdirectories under tests/data/, following the structure of the roborock.data module. Import statements across multiple test files have been updated from relative to absolute paths.

Key Changes

• Split container tests into three separate files organized by protocol type (general, v1, and b01_q7)
• Updated all mock_data imports from relative paths to absolute tests.mock_data imports
• Created snapshot directory for v1 container tests
