fix: use active login for existing sessions

[gobeyondpty]

Summary

• set generateLoginNode to send passive: false
• document why passive login is unsafe for existing companion sessions

Why

Real reconnect/import testing has shown WhatsApp can terminate login-node flows with 428 when the existing companion session is sent as passive. Registration already uses passive: false; login should use the same active mode for an existing session.

Checks

• git diff --check

I could not run the full project build in this clean worktree because dependencies are not installed and yarn is not available on the host.

Summary by cubic

Use active login for existing companion sessions by setting passive: false in the login payload. Prevents 428 rejections during reconnect/import and aligns login with registration behavior.

^{Written for commit 680f61a. Summary will update on new commits.}

Summary by CodeRabbit

• Bug Fixes
  • Updated login behavior so sign-in requests are sent in a more compatible mode, reducing the chance of rejection during authentication.

No more passive, login's complete,

This bunny hops on, code review nigh! 🐇✨
