Refactor webpush store tests and add coverage

- Add SetSubscriptionUpdatedAt to Store interface, remove DB() accessor
- Rename store files to store_sqlite.go and store_postgres.go
- Use camelCase for test function names
- Add tests for upsert field updates and multi-user removal
- Use transaction in setupNewPostgresDB
- Use lowercase "excluded." in PostgreSQL upsert query
