feat: add SQL migration for lucky echo and update foreign key constraints

- Introduced a new SQL migration file `0171_lucky_echo.sql` to modify the foreign key constraint on the `sso_provider` table, changing the `ON DELETE` behavior from `cascade` to `set null`.
- Updated the journal to include the new migration version and its associated tag.
- Added a snapshot file for version 7 of the database schema, reflecting the current state of the `sso_provider` and other related tables.

These changes enhance the integrity of the database by ensuring that user references are set to null instead of being deleted when the referenced user is removed.
