Automated dependency update to panther-analysis-tool v1.9.0

[cursor]

PR Summary

Low Risk
Routine dependency update with no breaking changes to detection logic; changes are isolated to tool versioning and related transitive dependencies.

Overview
Updates panther-analysis-tool from v1.8.0 to v1.9.0 in both Pipfile and Pipfile.lock, along with miscellaneous dependency updates (cffi, cryptography, filelock, idna, librt, moto, platformdirs, pre-commit, stevedore, virtualenv, and others).

The main user-facing change is that the "GSuite Drive Many Documents Deleted" detection was migrated from a scheduled query to a rule with an updated description reflecting improved detection logic (now detects bulk document deletions within 60 minutes rather than per-day). Index files were updated to reflect this change in analysis type and path.
