fix(clerk-js): retry load after stale dev browser

[brkalow]

Description

Fix Clerk initialization for development instances when FAPI rejects a stale development-browser value.

The environment request previously handled every failure as a cached-resource fallback, and its rejected settlement was not checked. As a result, an environment-only dev_browser_unauthenticated response could bypass the existing recovery loop. Clerk now clears the current development-browser value and retries both the environment and client requests.
