GIT13: the forge module keeps no trusted callers; who may call a verb is the seat definition's

The config value callers, the package seats' list of callers with its watch, and the seat git's caller judgement are gone:
the grants part grants by each definition's callers and the bus refuses the rest.

Builds: design 47 G §68, §127, §313, §321
