Covers the endpoint wired into the UI's "Add Account" dialog:
- Writes an Open directive to accounts/chart.beancount via Fava /api/source,
*unconstrained* by currency (the directive needs no currency list), with
provenance + description metadata (escaped for Beancount).
- Mirrors the account into libra's DB (synced_to_libra_db).
- Rejects duplicates with 409, malformed names with 400, and non-super-users

The harness ledger is the split layout (root includes accounts/chart.beancount)
