Button-driven bot management: paginated picker, per-bot API token /
revoke, Edit Bot (name/description/about/commands/botpic), Bot Settings
toggles (inline/groups/privacy), and delete. Navigation edits the menu
message in place via a new editServiceBotMessage helper.
Edit Botpic accepts a photo the user sends to @BotFather and sets it as
the bot's profile photo (new files.SetAvatarFromExistingPhoto, wired
through bots.SetBotUserpic / WithBotAvatarStore); photos.uploadProfilePhoto
does not accept a bot target so this is the only route.
Keep bot credentials out of durable command results, fail bot deletion closed when session revocation fails, reject invalid scam/fake states at every write boundary, and make direct collectible grants a single replayable PostgreSQL aggregate.
Also lock admin gift sender/message limits and add regression coverage for rollback, replay, moderation constraints, and credential redaction.
