Update cryptography with PyPy compatibility

[abrookins]

Summary

Updates the locked cryptography dependency from 46.0.5 to 46.0.7, carrying forward the previously approved patch update. The newer 48.0.1 Dependabot update cannot install in the supported PyPy 3.10 CI jobs, so this preserves the project test matrix while advancing the dependency.

Testing

• uv sync --all-groups --locked --python 3.11
• uv run --python 3.11 python -c import cryptography
• uv lock --check
• uv run --python 3.11 ruff check aredis_om tests
• uv run --python 3.11 ruff format --check aredis_om tests
• uv run --python 3.11 mkdocs build --strict

Breaking Changes

None.

Note

Low Risk
Lockfile-only patch bump of a transitive crypto library with no API or project code changes; typical low blast radius if CI passes.

Overview
Bumps the locked cryptography dependency from 46.0.5 to 46.0.7 in uv.lock only; no pyproject.toml or application code changes.

This is a patch-level security/maintenance update within the 46.x line, chosen so installs keep working on PyPy 3.10 CI jobs where newer major releases (e.g. 48.x) reportedly fail to resolve.
