Fix taxonomy term ID parsing in surveillance threshold sanitizer

[JLG-WOCFR-DEV]

Summary

• pre-process taxonomy surveillance thresholds to coerce term IDs from strings to integer arrays
• skip taxonomy thresholds that do not target any term when "apply to all" is disabled
• continue normalizing and persisting thresholds via the shared helper

Testing

• php -l liens-morts-detector-jlg/includes/blc-settings-fields.php

Preserve apply-to-all toggle when previous term IDs exist

The new sanitizer always parses term_ids even when the user selected “apply to all”. blc_normalize_surveillance_threshold_group later recomputes apply_to_all_terms purely from whether term_ids is empty. If a saved taxonomy threshold previously targeted specific terms and the user switches the checkbox to apply to all without manually clearing the textarea, the sanitized payload will still carry the old term_ids array and normalization will flip the flag back to false. The user therefore cannot change an existing threshold to apply to all terms unless they also clear the term IDs field, which the UI may hide. Consider clearing term_ids when $apply_to_all is true before handing off to the normalizer.
