fix(vercel): fix remaining No->false truthy-string dropdown bugs

- checkRerequestable, checkAutoUpdate, envVarsDecrypt dropdowns used id: 'false' for their No option (a truthy non-empty string), causing the conditional spread to always fire and explicitly send false instead of omitting the param
- swept the whole file for this pattern; checkBlocking correctly keeps 'false' since it's a required field that's always sent directly, not conditionally
