Pull request overview

Removes the dedicated VITE_REDIRECT_URL configuration and updates the frontend auth flow to preserve/restore the user’s current path via a safe redirect query parameter.

Changes:

• Removed VITE_REDIRECT_URL from setup types/loader, generated .env files, examples, and GitHub Actions workflows.
• Added safe redirect parsing + callback URL building utilities (getRedirectPath, buildCallbackURL).
• Updated SessionCheck/Login/Header/SocialLink to use VITE_CLIENT_URL and the redirect query param for post-auth navigation.

The UI can briefly show the "ログイン" link even for authenticated users: isSuccess can become true before the async generateIdenteapot(...) finishes and sets identicon, so the ternary falls into the login branch until identicon is populated. Consider rendering the login link only when the session check is definitively unauthenticated (e.g., isError), and render nothing/placeholder while isPending or while isSuccess but identicon is still loading.

The inline example URL in this comment hard-codes a specific production domain (pay-crew2.yukiosada.work). This can become outdated/misleading for other environments; consider using a generic placeholder domain (e.g. https://example.com/...) or describing the shape of the URL without a concrete host.
