Fix entry_id mismatch between castle links and exp/rcv links

Pass entry_id from views_api.py to format_expense_entry and
format_receivable_entry so that all links use the same ID:
- ^castle-{entry_id}
- ^exp-{entry_id} / ^rcv-{entry_id}
- entry-id metadata

Previously, views_api.py generated an entry_id for castle-* links
but didn't pass it to the format functions, which generated their
own separate IDs.
