review: clear stale attribution, gate numberless PUTs, cite the ADR

A Poll finding a higher number now clears series.latest_raised_by: the value
it stores is its own, so the next Poll must not credit that Reader with an
agreement they did not earn, nor charge them for a retraction of a number
they never reported.

A PUT carrying no chapter is no Sighting and defers nothing. The ceiling now
counts the Site's own rest rather than defaultRest. The userscripts PUT an
unchanged read too - the case the whole mechanism exists for was the one they
never sent.

ADR-0011 carries its citations and states honestly when a Reader's marks take
effect.
