fix: force $sequence to VAR_INTEGER and accept integer IDs in UUID7 mode

- Structure validator: force $sequence (not $tenant) to VAR_INTEGER since
  sequences are always auto-incrementing integers
- Sequence validator: fall through from UUID7 to integer validation so
  VAR_ID attributes like $tenant can be integers in any adapter
