Migrate date precision handling tests

Update park and ride submission forms to support and persist all new date precision options (exact, month, year, decade, century, approximate), ensure default and validation align with backend, and verify submissions save without errors. Includes front-end tests scaffolding and adjustments to submission helpers to store updated precision fields.
