fix(android): retain HTTPS sessions with upstream default cookie flags

Reproduce browser-success/native-401 with unmodified upstream SESSION_SECURE=false behind HTTPS. Keep cookies in the existing HTTPS-only origin-bound encrypted jar regardless of the server Secure attribute; preserve TLS, redirect, expiry and origin protections. Distinguish credential/2FA rejection from missing/rejected session handoff and clear stale login errors on retry. Verify 13 JVM tests plus the 7-test real-server suite in both Secure/default-cookie modes, including bad-password then successful native login. Bump Android preview to 0.2.1/code 3; extend CI and document the defect without claiming access to the user's production server.
