MariaDB default collation is case-insensitive on VARCHAR unique indexes,
so 'L' and 'l' clash on units_company_id_code_unique. When a tenant had
'L' in parts.unit (uppercase) and the migration seeds 'l' (lowercase),
the extras loop tried to re-insert 'L' and errored out — blocking all
subsequent migrations (including the new injector_protocols tables).
Fix: lowercase the comparison + switch the extras insert to
insertOrIgnore so a residual race is a no-op.
