### What problem does this PR solve?

Change the condition from checking for >1 to >=1 when validating
duplicate knowledgebase names to properly catch all duplicates. This
ensures no two knowledgebases can have the same name for a tenant.

### What problem does this PR solve?

- Rename `api_key` fixture to `HttpApiAuth` across all test files
- Update all dependent fixtures and test cases to use new naming
- Maintain same functionality while improving naming clarity

The rename better reflects the fixture's purpose as an HTTP API
authentication helper rather than just an API key.

Issue: #8051

The current implementation assumes JWKS endpoints follow the standard
`/.well-known/jwks.json` convention. This breaks authentication for OIDC
providers that use non-standard JWKS paths, resulting in 404 errors
during token validation.

Root Cause Analysis
- The OpenID Connect specification doesn't mandate a fixed path for JWKS
endpoints
- Some identity providers (like certain Keycloak configurations) use
custom endpoints
- Our previous approach constructed JWKS URLs by convention rather than
discovery

### Solution Approach
Instead of constructing JWKS URLs by appending to the issuer URI, we
now:
1. Properly leverage the `jwks_uri` from the OIDC discovery metadata
2. Honor the identity provider's actual configured endpoint

```python
# Before (fragile approach)
jwks_url = f"{self.issuer}/.well-known/jwks.json"

# After (standards-compliant)
jwks_cli = jwt.PyJWKClient(self.jwks_uri)  # Use discovered endpoint
```

### What problem does this PR solve?

Currently, as long as there are tasks in Redis, this loop will keep
getting the tasks. This will lead to a single task executor with many
tasks in the pending state. Then we need to wait for the pending tasks
to get them back in the queue.

In first place, if we set the `MAX_CONCURRENT_TASKS` to X, then only X
tasks should be picked from the queue, and others should be left in the
queue for other `task_executors` or be picked after 1 of the spots in
the current executor gets free. This PR ensures this behavior.

The additional changes were due to the Ruff linting in pre-commit. But I
believe these are expected to keep the coding style.
