fix: address CodeRabbit review feedback

- Remove overly broad 'invalid' check (can match PKCE errors, not just expired tokens)
- Rename handleSendNewLink → handleShowEmailForm (more accurate)
- Remove unused isLoading/linkSent props from ExpiredLinkMessage
- Simplify ExpiredLinkMessage component (single prop)
- Encode catch block error parameter for consistency
