Add $tries = 3 to tenant lifecycle jobs

Adds a bounded retry count to CreateDatabase, MigrateDatabase,
DeleteDatabase, and SeedDatabase. Without $tries, and with
queue:work --tries=0 (the default on some platforms including
Vapor pre-2.4.1), these jobs retry indefinitely when the tenant
database is briefly unreachable.

DeleteDatabase is the highest-risk case in the four: if the DB
server blips mid-delete, the job loops against it, and any replays
after recovery hit a database that may have been partly deleted
or may contain data the tenant wanted preserved.

`$tries = 3` bounds retries at three attempts; workers then
surface the failure to failed_jobs for operator review rather
than looping.
