fix(rule-engine): merge duplicate Sebeta yards, block dupes

Two active Sebeta yards (LEGACY_DEST/'Sebeta' and SEBETA/'sebeta')
split rates and routes across different yard ids, so route-scoped rate
lookups missed. Migration repoints every yard reference to the survivor,
retires the duplicate, and adds partial unique indexes on active label
and code. Service now rejects case-insensitive duplicate labels on
create/update - the old guard only compared generated codes, which
missed labels whose existing code differs (LEGACY_DEST).
