Problem

Opening a transcript in the viewer took about 10 seconds on Linux, sometimes with an "is not responding" prompt. Every get_password() call blocked for 5 seconds in _get_portal_secret(), and opening the viewer makes two of them (the viewer itself and Translator.__init__).

The portal sends a Response signal on the request object. When it refuses the request (seen with xdg-desktop-portal 1.21 for an app that is not sandboxed, response code 2), it never writes the secret. We didn't listen for that signal and waited for the full 5 second socket timeout instead.

Fix

• Subscribe to the portal's Response signal and return straight away when the code is non-zero, without reading the socket.
• Cache the portal secret, or its absence, for the lifetime of the process. It is fixed per app and get_password() is called from many widgets.
• Close the D-Bus connection, which was previously leaked.

The first lookup now takes about 70ms, down from 5s, and later lookups take under 1ms.

Tests

New TestPortalSecret tests in tests/store/keyring_store_test.py cover the success path, a failed response returning without reading the socket, the caching, and non-Linux.
