fix(platform): Turnstile CAPTCHA reset after failed login attempts (#10056)

Users were unable to retry login attempts after a failed authentication
because the Turnstile CAPTCHA widget was not properly resetting. This
forced users to refresh the entire page to attempt login again, creating
a terrible user experience.

Root Cause: The useTurnstile hook had several critical issues:

- The reset() function only cleared state when shouldRender was true and
widget existed
- Widget ID tracking was unreliable due to intercepting
window.turnstile.render
- Token wasn't being cleared on verification failures
- State wasn't being reset consistently across error scenarios

Changes 🏗️

<!-- Concisely describe all of the changes made in this pull request:
-->

- Fixed useTurnstile hook reset logic: Modified the reset() function to
always clear all state (token, verified, verifying, error) regardless of
shouldRender condition
- Improved widget ID synchronization: Added setWidgetId prop to the
Turnstile component interface and hook for reliable widget tracking
between component and hook
- Enhanced error handling: Updated handleVerify, handleExpire, and
handleError to properly reset tokens on failures
- Updated all auth components: Added setWidgetId prop to all Turnstile
component usages in login, signup, and password reset pages
- Removed unreliable widget tracking: Eliminated the
window.turnstile.render interception approach in favor of explicit
prop-based communication

- [x] I have made a test plan
- [x] I have tested my changes according to the test plan:
- <!-- Put your test plan here: -->
- [x] Test failed login attempt - CAPTCHA resets properly without page
refresh
- [x] Test failed signup attempt - CAPTCHA resets properly without page
refresh
	- [x] Test successful login flow - CAPTCHA works normally
