Remove Cards from Price Watchlist

Remove watchlist entries (batch), or clear the whole list.

Request fields:

• items — list. Entries to remove (max 100). The grade must match the stored entry exactly: an all-grades entry is removed by omitting grade_label; a "PSA 10" entry is removed by passing "PSA 10".
• clear_all — boolean. Remove every entry.

Exactly one of items or clear_all is required; passing both is rejected with HTTP 400. Removing an entry stops its updates immediately. removed is the count of entries actually deleted (already-absent items simply count zero).
