Enforce unique names on sequence parcels

[cartermak]

Checked for duplicates

No - I haven't checked

Is this a regression?

No - This is a new bug

Version

v3.5.2

Describe the bug

Turns out you can create multiple parcels with the same name, which is confusing because there's no way to tell the difference when creating a sequence/workspace.

The DB should enforce a uniqueness condition for parcel names.

Reproduction

Create two parcels with the same name.
