fix: remove pre-Phase4 volume tenant fallback

Browse Source 
Simplify all 6 tenant-check sites in volume handlers from
`if accountID != "" && tenantID != "" && tenantID != accountID`
to `if tenantID != accountID`. No pre-Phase4 volumes with empty
TenantID exist in any environment — this code was unreachable.
Remove vol-legacy test fixture and empty-accountID-sees-all assertion.
