Completes the provisioner's write path. internal/tg drives BotFather as a
conversation rather than pretending it is an endpoint, creates channels,
claims usernames with fallbacks, and grants post_messages. internal/apply
sequences it: bot before administrator, test channel before public, and
state saved after every step that changed the world -- a channel that
exists but is unrecorded is worse than one that does not exist, because
the next run creates a second.
The operator session lives in OpenBao, not on disk. gotd's FileStorage
would leave a full-account credential in the working directory, where it
outlives the run and can be committed by accident.
The bot token goes straight from BotFather's reply to OpenBao and is
cleared from memory; if that write fails the error says how to recover by
hand and warns against re-running, since a retry creates a second bot.
Closes T05: the redaction salt is create-if-absent with no overwrite path,
and the test asserts it, because rotating it invalidates every longitudinal
comparison with no visible failure.
