fix(webauth): improve error messages around webauth in non-TTY (#8952)
## Add webauth URLs to EOTP error messages When npm returns an EOTP error with `authUrl` and `doneUrl` in the response body (web-based OTP flow), these URLs are now included in the error output. **What:** - Display `authUrl` (for browser authentication) and `doneUrl` (for token retrieval) in non-TTY EOTP error messages - Include both URLs in `--json` output as `error.authUrl` and `error.doneUrl` - Adjusted messaging to differentiate webauth flow from traditional TOTP authenticator flow **Why:** - In non-interactive/CI environments, the webauth URLs were not surfaced, making it impossible to complete authentication - Tools wrapping `npm publish` (like [changesets](changesets/changesets#1773)) need access to these URLs to implement web OTP support - The `doneUrl` is required for polling to retrieve the token after browser authentication completes
