fix(webui): app-log removal uses runFileOp rm -f so uninstall can't hang

The uninstall branch of webuiUpdateAppLog removed the per-app WebUI log
with a bare `rm`. The log lives in the container data plane and is owned
by the container user, often without a write bit. A bare rm (run as root
via `sudo init.sh uninstall`) prompts interactively for write-protected
files — which hangs an otherwise-unattended deploy: the uninstall phase
of a `full` redeploy stopped dead at "rm: remove write-protected regular
file '.../frontend/logs/apps/<app>.log'?".

Route it through runFileOp rm -f (as the container-data owner, force) to
match the neighbouring uninstall_app.sh and the install branch's
owner-aware createTouch/runFileWrite helpers. No prompt, correct owner.
