fix(api): remove logfire from api server

[inimaz]

There is an error in the API server that keeps popping up.

The error

2026-02-08T14:54:01.571Z
Caught an internal error in Logfire. Your code should still be running fine, just with less telemetry. This is just logging the internal error.

...

AttributeError: module 'pydantic' has no attribute 'RootModel'

What it means

Logfire is using pydantic v2 whereas the carbonserver is using pydantic v1. They are not compatible.

The solution

Remove logfire from the installed packages (it was not running anyhow). We will reactivate it when we migrate to pydantic v2.

Thanks, logfire free plan was also deprecated. However I think we could migrate to pydantic v2 without breaking change, could you test it from this PR ?

[inimaz]

Info about the migration to pydantic v2 --> #1056

[SaboniAmine]

OK lets do it in a separate PR!

[inimaz]

Just saw your comment after @SaboniAmine sorry!

logfire free plan was also deprecated

then I can remove logfire entirely n?
