feat(seeder): add truncate before seeding for clean state

Add TRUNCATE TABLE statements with RESTART IDENTITY CASCADE to all
seeder
SQL files to ensure tables are emptied and primary keys reset before
inserting seed data. This guarantees a clean database state for each
migration:fresh run. Also update registration_events seeder to include
"id" in insert columns and values for consistency.
