- Edit Bot now shows the current value of every field (Name/About/
Description/Botpic/Commands) like BotFather, with real botpic status
via a new PeerHasAvatar port method.
- After editing a field the dialog lands back on a fresh Edit Bot menu
(working "Back to bot" / "Bots list" buttons) instead of ending, so a
follow-up button press no longer reports the button as expired.
- Service-bot messages now render @username as a tappable mention entity.
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.
A channel post containing an @token that is not a syntactically valid
username (too short, leading digit, etc.) made messages.sendMessage return
500 INTERNAL_SERVER_ERROR: mentionedUserIDsFromMessage turned every
ResolveUsername error into internalErr().
Skip tokens that fail with ErrUsernameInvalid / ErrUsernameNotOccupied
instead, matching real Telegram (the message sends, the client renders the
mention and only fails to open it on tap). Only unexpected storage errors
still abort. Same fix applied to the bot send path.
The "*" wildcard was never in assignablePermissions, so an operator holding it
(the one the first-run wizard creates) showed every box unticked while having
every right, and there was no way to take it away. Its own row fixes both; the
grid is disabled while it is on, since normalisePermissions collapses "*" plus
anything back to "*".
That made guardManagerRemoval reachable from the UI for the first time, so it
now has an integration test covering the wildcard match and the enabled filter
in its SQL.
