### What problem does this PR solve?

This PR investigates the cause of #7957.

TL;DR: Incorrect similarity calculations lead to too many candidates.
Since candidate selection involves interaction with the LLM, this causes
significant delays in the program.

What this PR does:

1. **Fix similarity calculation**:
When processing a 64 pages government document, the corrected similarity
calculation reduces the number of candidates from over 100,000 to around
16,000. With a default batch size of 100 pairs per LLM call, this fix
reduces unnecessary LLM interactions from over 1,000 calls to around
160, a roughly 10x improvement.
2. **Add concurrency and timeout limits**: 
Up to 5 entity types are processed in "parallel", each with a 180-second
timeout. These limits may be configurable in future updates.
3. **Improve logging**:
The candidate resolution process now reports progress in real time.
4. **Mitigates potential concurrency risks**

This change makes pagerank a mutable property that can only be set after
dataset creation, and only when using elasticsearch as the doc engine.

### Type of change

### What problem does this PR solve?

Validate that pagerank updates are only allowed when using elasticsearch
as the document engine. Return an error if pagerank is set while using a
different doc engine, preventing potential inconsistencies in document
scoring.

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
```
