Mathieu Fenniak 81cce58a48 migration: update existing foreign key migrations to automatically fix inconsistencies (#10568)
Changes foreign key database inconsistency handling so that inconsistent records are automatically deleted with an administrator warning during migration.  As noted in discussion: https://codeberg.org/forgejo/discussions/issues/385#issuecomment-9175566

Intended for backport to v14 to eliminate pain during upgrades.

Because these migrations are now deleting data, rather than allowing the administrator to do it, all migrations have been covered with an integration test that verifies expected data is deleted.  This is particularly interesting with nullable fields.
