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.
