test: isolate QSettings in GUI tests so they never touch the real ~/.config/8cut

Browse Source 
Constructing MainWindow loads and (on close) re-saves the playlist tabs; a test
that mutated tab state could persist into the user's real session. Redirect
QSettings to a temp dir at import time.

# (constructing MainWindow loads — and on window close re-saves — the playlist
# tabs; a test mutating tab state would otherwise persist into the real session).

# A real platform is needed because MpvWidget creates a GL context.
# If construction fails for any environment reason, skip — this test is a
# best-effort structural net, not a gate on core/ tests.
