Every bot notice carries a Hide button, which deletes the message it sits on.
On a backup that message is the file itself: one tap, with no confirmation,
could remove the admin's only copy of the database. Backup files (the .db and
config.json, from the backup button, the scheduled job and the panel's
backup-to-Telegram endpoint) are now sent without a keyboard; other notices,
including the ban log file, keep Hide.
The backup button also left the menu above the files it sent, out of view at
the bottom of the chat. It now sends the Maintenance menu again below them and
removes the old one. A scheduled backup leaves the menu where it is.
The bot answered every action with a new message, so a chat filled with stale
menus whose buttons still acted, and long client or inbound lists were paged
through dozens of buttons. Each chat now has one live screen that is edited in
place: the menu is grouped into Server, Clients, Traffic and Maintenance, lists
open through inline search, the add-client flow starts from a draft card, QR
codes arrive as one labelled sheet, and repeated notices collapse into one with
a counter. A client's /start and /usage show only that client's own links and
usage, groups are refused, and the settings page warns when the bot's inline
mode is off. Admin topics, the indexed Telegram lookup and every locale,
Slovak included, carry over.
