PR Summary

Low Risk
Scoped startup migration deleting a fixed legacy table and file; failure modes are mostly I/O or MDBX drop errors during open, not changes to live state paths.

Overview
On storage open, nodes that still have pre-migration artifacts from when state commitment infos lived in storage get a one-time cleanup: the legacy MDBX table state_commitment_infos and the on-disk file state_commitment_infos.dat are removed before normal table setup.

New DB helper DbWriter::drop_table_if_exists opens a short RW transaction, drops the named table when present (returns whether anything was dropped), and treats NotFound as a no-op—intended for schema tables that older databases may still carry.

Tests cover full table removal (not just emptying) and an integration test that seeds the legacy table/file and asserts open_storage clears both.
