Consolidate all paths to plugin flash dir, fix watchdog 7.3 triggers

- Move SCRIPTS_DIR/DATA_DIR/STATE_DIR from appdata to /boot/config/plugins/varaverk
- All state files now in STATE_DIR (no more /tmp or /boot/config root writes)
- Bootstrap: Gitea-first clone with GitHub fallback, no array dependency
- varaverk.cfg seeded with Gitea connection settings
- .gitignore: add State_Files/, varaverk.cfg, varaverk-*.txz
- Partnership/transcode/fallback scripts use STATE_DIR variables
- PHP config.php: DATA_DIR/STATE_DIR constants, VV_SETUP_STATE_FILE dynamic
- deploy.sh PROD_ROOT updated to plugin flash dir
