Context: Wealthfolio 3.2 generates its own UUIDs on POST /accounts, ignoring any
`id` we supply. Our logical Account.id lives on as `providerAccountId`, which
WF preserves verbatim.
Live run created six duplicate accounts because ensure_account looked up by
our `id`, never found it, and POSTed a new account on every attempt. Deleted
the duplicates manually via DELETE /accounts/{id}.
This change:
- ensure_account now returns Wealthfolio's UUID; matches existing via
(provider, providerAccountId)
- pipeline remaps activity.account_id to the WF UUID at submission time
but keeps dedup keyed on our stable id (WF resets must not blow away
the whole dedup history)
- test updates to the new account-shape + dedup key expectations
