Pull request overview

This PR addresses a login failure when Charon is accessed over plain HTTP via a private-network IP by (1) ensuring the backend does not set Secure=true cookies for local/private HTTP requests and (2) adding a frontend Bearer-token fallback for session validation.

Changes:

• Expand backend “local request” host detection to treat RFC1918/IPv6 ULA IPs as local, so HTTP logins from private IPs can receive usable (non-Secure) auth cookies.
• Add Authorization: Bearer <token> fallback to fetchSessionUser() so /api/v1/auth/me can succeed even if cookies are not available/accepted.
• Add/extend backend tests and add QA/spec/manual test documentation for issue #825.
