🔧(helm) adapt helm chart

Done:
- Rename all occurrences of "impress" to "meet".
- Update Agent Connect secrets credentials for the dev environment.
- Add new development secrets for LiveKit.
- Remove Minio from the dev stack (no cold storage required).
- Add LiveKit chart to the stack.
- Remove templates and values related to the WebSocket server.

The integration of LiveKit was inspired by an example from the "numerique-gouve/infrastructure" repo.
However, a notable issue persists with LiveKit's default chart: we are unable to override
the namespace, resulting in all LiveKit components running in the default namespace.

thx to @rouja for his help.
