Two follow-ups from a contour test where a user joined the chat, then
registered, and got no write access — with silent logs.
Observability: log every chat_member update (chat id, configured id, user,
old->new status), the eligibility result and the grant outcome; plus a startup
self-check that warns loudly when the bot is not an administrator in the chat
with the restrict-members ("Ban users") right — the common misconfiguration,
previously invisible in the logs.
Grant on first registration: a user who joins the moderated chat BEFORE
registering is covered by no chat_member event, so the join-time grant never
fires for them. ProvisionTelegram now reports first contact, and the Telegram
auth handler emits chat_access_changed on it, so the gateway re-evaluates and
grants write access if the user is already in the chat.
