BlueSky custom name / domain handle not being supported

[IrealiTY]

📜 Description

It seems that if you use a custom domain handle a la mydomain.com instead of the typical name.bsky.social handle, postiz won't properly submit posts via the API. Logging in to Postiz works fine tho.

👟 Reproduction steps

1. Login to postiz via customdomain.com and an App Password
2. Try to submit a post
   2.1. it will show as sent
3. after a few seconds, it will throw a fail notification

👍 Expected behavior

A successful post.

👎 Actual Behavior with Screenshots

💻 Operating system

Linux

🤖 Node Version

v20.17.0
