Code Review

This pull request introduces a utility for managing callback URLs and integrates it into the login, registration, and invitation flows to maintain user context across authentication steps. A critical issue was identified in the registration hook where the verification callback URL was overwriting the required email verification endpoint; suggestions were provided to correctly append the destination as a parameter instead.

[gemini-code-assist]

The current implementation replaces the email verification URL entirely with the verificationCallbackUrl. This will break the registration flow because the user will be directed to a page (like /dashboard or /invite/...) that does not handle the email verification token. Instead, the callbackURL sent to the auth provider should point to the verification endpoint, which then handles the redirection to the final destination.

Suggested change

	callbackURL: verificationCallbackUrl
	? new URL(verificationCallbackUrl, window.location.origin).toString()
	: `${window.location.origin}/auth/verify-email`,
	callbackURL: verificationCallbackUrl
	? appendCallbackUrl(`${window.location.origin}/auth/verify-email`, verificationCallbackUrl)
	: `${window.location.origin}/auth/verify-email`,

Import appendCallbackUrl to correctly construct the email verification URL with the target callback destination.
