fix(settings): fee only from fee_service_charge_percentage; deploy:tenant

Remove service_charge_percentage alias and config/fee.php fallback (empty → 0).
Move code-managed Montzar/price runtime keys to can_edit=1 in deploy SQL.
Add settings:deploy and deploy:tenant artisan commands for server deploy.
Advanced admin settings merge runtime keys from local DB; block manual edits.
