dev.knotless.deleteAccountData

Deletes the asking account's knotless data a part at a time, as `knotless account delete-data` does: first the spaces of its private repositories, then each public repository as dev.knotless.deleteRepo deletes one, then whatever is left in its dev.knotless.* collections. Asked by the pages' session cookie, it deletes with the session the appview keeps for the account, up to `limit` records and spaces a call, and answers whether it is done; the pages ask again until it is, and a run cut short carries on where it stopped. Once nothing is left, the appview drops what it indexed from the account, as for one deleted at its PDS, keeping its takedowns and reports about it, and ends the account's sessions here, the pages' and MCP's, logging the browser out. Asked with a service token, as the command line asks once it has deleted the records itself, it deletes nothing, and forgets the account only once its PDS holds no knotless records. The atproto account itself, and other apps' records in it, are untouched. Only the account itself can ask.
