wolf: fix cemu-sync-controllers silently finding zero joysticks

Claude 93efe0d607 wolf: fix cemu-sync-controllers silently finding zero joysticks 
docker exec needs an explicit -i flag to forward stdin into the
container process; without it, the heredoc piped into `python3 -`
never reached the containerized script, which ran empty and printed
nothing. cemu-sync-controllers then misread that empty output as
"SDL reported zero joysticks" — a false negative with a working set of
4 controllers already confirmed live in ES-DE, not an actual SDL or
GUID problem. Root-caused against the user's own live output: the
exact same probe script, run directly (not via the manage.sh command),
found real device nodes (js0-js4) present in the same container at the
same time cemu-sync-controllers reported zero.

Audited every other docker exec call in this file for the same
stdin-via-heredoc pattern; this was the only one missing -i.
