Arda Samadi 485f8d460a Security fixes: session hardening, open redirect, SSR path injection
- sessions: require REMIX_SECRET in prod (no "secret" fallback); base Secure
  cookie on NODE_ENV; add maxAge
- login: safeRedirect() blocks open-redirect via redirectTo (loader + action)
- SSR loaders: encodeURIComponent on user path params before internal API
  fetch (product, store product, seller)
