fix(eims): retimestamp the EIMS migration to 3330000000000

3300000000000 collided with BookingWagonCancellations after the rebase.
3320000000000 is also unavailable: BulkContractTemplates3320000000000 is
already recorded in freight.migrations on the shared dev database from a
branch not present in this checkout, so checking only src/migrations is not
sufficient.

3330000000000 is unique across src/migrations and greater than the current
maximum timestamp recorded in freight.migrations.

Rename the migration file and class. The migration has no explicit name field
and no other code references its previous identity.

Verify migration discovery through the actual runtime path:
scripts/migrate.js loads compiled dist/migrations/*.js migrations, while
application boot does not run migrations automatically. Confirm the renamed
migration is present in dist.

For controlled dev verification, remove its migration-history row and run
pnpm migration:run again. The migration is discovered and applied under
3330000000000; its idempotent DDL produces no schema changes where the EIMS
schema already exists.
