The poll this page's pairing block rode was retired hours earlier by
f8e07a332, which moved Messaging onto platforms.changed. That signal is the
mtime of gateway_state.json — where the gateway persists connect/disconnect
health — and a new pairing request moves none of it. So on an event-capable
backend a pending row stayed invisible until something unrelated
reconnected, and the count badge with it.
Adds pairing.changed to the change watcher, signed off the pending/approved
ledgers across the global store and every profile's own. _rate_limits.json
is deliberately excluded: it moves on every unauthorized DM, including ones
that produce no new row, so signalling on it would refetch for nothing.
The page now refreshes platforms and pairing on their own signals rather
than one combined call, and the legacy visible-tab poll (older backends)
covers both.
