list: sold listings are reported as "active"

[untitaker]

Description

willhaben list shows Status: active for listings that have already been sold.

Steps to reproduce

1. Mark a listing as sold on willhaben
2. Run willhaben list (or willhaben list --json)
3. The sold listing is still reported as active

Actual behavior

On my account, 27 of 28 listings that are sold are reported as active:

$ willhaben list --json | jq -r '.listings[] | "\(.status)\t\(.title)"'
active    <sold item A>
active    <sold item B>
inactive  <sold item C>
active    <sold item D>
...

Interestingly one of them does come back as inactive, so the behaviour is not
uniform across listings.

Expected behavior

Sold listings should be distinguishable from active ones.

Note that Listing["status"] currently has no sold variant — src/api/listings.ts
maps sold onto "inactive", so even when the status is picked up correctly a sold
listing cannot be told apart from one that is merely inactive. A dedicated sold
status would be useful.
