fix: add default_qry_str to db_events Event interface, remove incorrect global augment

The field exists on the DB object but was missing from the TypeScript interface,
causing a false error in recovery_meetings search. Added it to db_events.ts where
it belongs. Removed the incorrect global DOM Event augment from the temp augments
file (was patching the wrong interface).
