Orgchain v1.14.1: a belt counts only on its seat's own sat

Placement is now a rule of lineage/v0, not just how Orgchain inscribes:
an award counts only if it is inscribed on its recipient's own sat, so any
indexer can check that a belt is soulbound. The reducer compares sats
(satOf): the lab's sat numbers, ord's, or, without ord's sat index, its
satpoints, which two inscriptions share exactly when they share a sat. ord
events now carry the sat number when ord has one. Belts inscribed anywhere
else, as before v1.14, are rejected.

A promotion is another reinscription on the same sat, over the belt before
it: each badge keeps its skill's earlier belts, and Inspect shows the
ladder ("re-inscribed over white (beat 5)"). The sample's sol now goes
white, then green. An award and its recipient's own close no longer
conflict within a block, since both spend the recipient's inscription.

Rehearsed again on Bitcoin Core regtest from height 178: sixteen beats and
133 transactions; ord shows sol's sat carrying sol, its white belt and its
green belt, in order, each belt charmed reinscription and vindicated, and
the compare matches. The fixture is re-recorded.
