Introduces a wildcard-based match type that supports prefix, suffix,
and sandwich patterns (e.g. ph_phc_*_posthog). The SQL matching uses
starts_with/ends_with on the parts split at '*', avoiding LIKE and
its underscore escaping issues. Existing PREFIX rows are migrated to
GLOB with a trailing '*'.
