Listing a Telegram account's clients ran CheckIsEnabledByEmail and
describeAttachedInbounds for every client, and both loaded and parsed
the client's entire inbound, so one message cost the number of clients
times the size of their inbound's settings.
CheckIsEnabledByEmail now reads the client's own record first, keeping
the inbound parse only for legacy clients never normalized into the
clients table, and describeAttachedInbounds takes every remark in one
query without loading any settings.
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.
