self-delete: use the full delall sweep, require the PIN

POST /delete now runs lib/deluser, the same sweep as scripts/delall.ts:
it also disables the account's bolt12 offers on the node, removes the
invoice pointer keys (invoice:<hash|text|offer_id>), covers sub-account
invoices and deletes from the archive too. Offers are disabled before any
key is deleted, so an unreachable node aborts with the account intact.
Accounts with a PIN must now send it.
