Fix wolf.sh manage.sh apps: detect installed apps regardless of indentation

INSTALLED=$(sudo grep "^    name = 'Wolf" ...) required exactly 4 leading
spaces before name = 'Wolf...' in Wolf's own generated config.toml.
Confirmed live: Wolf's TOML writer doesn't reliably indent that way, so
this came back empty even with apps clearly installed and running,
printing "No Wolf apps installed yet". That's silently wrong in two
ways: the "Already installed: ..." message under-reports, and pressing
Enter at the apps prompt ("update mounts only") falls through to the
hardcoded `steam esde` default instead of actually refreshing whatever
was already there — so a mount fix for an already-installed app (e.g.
RetroArch) never gets applied by the Enter/no-picks path at all.

Relaxed the anchor to tolerate any amount of leading whitespace,
matching the Python injector's own already-installed check a few lines
later, which never anchored on indentation to begin with.
