Test: regression for SQLite rollup node store schema

What

This MR introduces adds a test that captures the schema of a new rollup node in a regression.

This MR also adds a check in the CI to ensure migration files are not changed. When adding a new migration, one should call

scripts/check_rollup_node_sql_migrations.sh promote

Why

This is analogous to what is done in the EVM node and ensures that we do not change the store without a migration.
