Fix WORK_DIR override: config file was clobbering detect_mode

The settings screen wrote WORK_DIR="/usr/local/gniza/workdir" (root-mode
path) into gniza.conf. load_config then overrode the correct user-mode
path set by detect_mode, causing mktemp and rsync log redirects to fail
with Permission denied — crashing the bash script while rsync continued
as an orphan.

- Remove WORK_DIR from AppSettings model and settings screen
- Re-run detect_mode after config load to restore correct paths
- Removed stale WORK_DIR from user's gniza.conf
