Pull Request Overview
This PR enables diff-informed data flow in several experimental Python security queries by adding getASelectedSourceLocation(...) { none() } overrides where only source or sink locations are selected.
- Introduces an empty override for source location in diff-informed incremental mode.
- Applies the override consistently across four security analysis modules.

- Consider adding tests to verify that diff-informed incremental mode correctly skips source locations via this override.

[nitpick] This override is identical in multiple config modules; consider extracting a shared mixin or base module to provide the default none() override and reduce duplication.
