fix: add 'use client' to routing-forms components to resolve React error 185 (calcom#25107)

Adds 'use client' directive to FormInputFields.tsx and widgets.tsx in the
routing-forms package. These components use React hooks (useLocale, setState)
but were missing the client directive, causing React error 185 (invalid hook
call) in production builds due to Next.js App Router bundling differences.

The error only occurred in production, not local dev, because production
builds optimize and bundle packages differently. The widgets.tsx file uses
the useLocale hook in the Button component, and FormInputFields.tsx passes
state setters to child components.

Fixes the reroute dialog error reported in production.
