GORM adds deleted_at IS NULL to these queries, and SQLite, which has no
table statistics here, preferred the deleted_at index to the new
single-column ones wherever a column is matched against several values
or compared with <. The event log's attempt load, retention's lookups
of expired events and their deliveries, and the queue-depth sampler
still read every live row. Each index now also covers deleted_at,
first in the events index because created_at is compared with <;
events keeps its created_at index for retention's final delete. A test
checks SQLite's plan for each statement as GORM builds it.

Re-align the json tag column in DeliveryResult after the wider
DeliveryID gorm tag, and move the test's index table out of package
scope into the test function.

The per-webhook tables declared no secondary indexes, so the recovery
and sweep queries (by delivery status, every minute), the event log
(deliveries by event, results by delivery) and retention (events by
age) each scanned a whole table. Add indexes through GORM model tags so
AutoMigrate creates them on a fresh and on an existing per-webhook
database. events.created_at is indexed by overriding the embedded
BaseModel field on Event alone, leaving the other tables' created_at
unindexed. A test drops the indexes from an opened database, reopens it,
and asserts the open recreated them. The README Data Model section lists
the indexes.
