feat: always log StaleMARC/suppressions-DB report skips (#438)

Previously every skip reason (StaleMARC, the suppressions DB, and
NoReportsList) was only printed under --verbose, so a report silently
skipped via StaleMARC or the suppressions table left no trace in a
normal cron run. NoReportsList stays --verbose-only since it's
operator-curated and the operator already knows what's in it; the
other two are dynamic/external and worth surfacing by default.

 The script checks the

 The table is loaded once at startup and is not queried per-message, so
 changes take effect on the next run.  If the table does not exist (e.g. on
 a pre-migration install) the check is skipped and a notice is written to
