Saved cloud credentials can't be decrypted after re-login

[vsilent]

Description

After logging out and back in to Stacker, saved cloud credentials fail to decrypt:

Using saved cloud credentials (id=1, provider=htz)
Error: Cloud API credentials could not be decrypted. Please delete and re-add your cloud credentials.

Affected Projects

ArchiveBox, middleware

Steps to Reproduce

1. Login and save cloud credentials
2. Logout: stacker logout
3. Login again: stacker login
4. Try to deploy: stacker deploy --target cloud
5. Command fails with decrypt error

Expected Behavior

Saved credentials should persist across login sessions, or the CLI should prompt to re-add them.

Current Workaround

Use --key htz-0 flag to specify a different saved credential, or delete and re-add credentials manually.

Environment

• Stacker CLI version: latest
• Cloud provider: Hetzner
