enhanced security by default

### What do you want and why?

for streamers, blitz logs expose sensitive data by default on the terminal

### Possible implementation(s)

```
// Note: This stays in the /pages folder for the time being

import { rpcHandler } from "@blitzjs/rpc"
import { api } from "src/app/blitz-server"

const getBlitzLogLevel = (): "info" | "debug" | undefined => {
const requestedLevel = process.env.BLITZ_LOG_DISABLE_LEVEL
if (requestedLevel === "info" || requestedLevel === "debug") {
return requestedLevel
}
return undefined
}

export default api(
rpcHandler({
onError: (error, ctx) => console.log(error),
logging: {
disablelevel: getBlitzLogLevel(),
},
})
)

```
