## Description
Fixes connection error handling when langfuse service is unavailable.
The application now gracefully handles connection failures instead of
crashing.
## Changes
- Wrapped `langfuse.auth_check()` calls in try-except blocks in:
- `api/db/services/dialog_service.py`
- `api/db/services/tenant_llm_service.py`
## Problem
When langfuse service is unavailable or connection is refused,
`langfuse.auth_check()` throws `httpx.ConnectError: [Errno 111]
Connection refused`, causing the application to crash during document
parsing or dialog operations.
## Solution
Added try-except blocks around `langfuse.auth_check()` calls to catch
connection errors and gracefully skip langfuse tracing instead of
crashing. The application continues functioning normally even when
langfuse is unavailable.
