Describe the bug
When manually deploying a proxy outpost, it attempts to connect to Redis. This behavior is not intended and ak should not attempt to connect if the outpost is not marked as "managed". Ref: #6931 (comment)

To Reproduce
Steps to reproduce the behavior:

1. Set up a standalone Proxy outpost
2. Set it up with required env vars, get a token, ...
3. Attempt to start it. In some cases, this error will appear. Prior to 2025.2.x, everything worked fine except when it happened to me in November: https://discord.com/channels/809154715984199690/809154716507963434/1310351533271027763

Expected behavior
The outpost does not attempt to connect to redis
