Enable condenser and security analyzer as configurable options in EvalMetadata

[simonrosenberg]

Description

The Agent constructor in run_infer.py currently does not use the condenser or security analyzer. These should be enabled and made configurable via EvalMetadata.

Specifically, we should support:

• condenser — using get_default_condenser() with a dedicated service_id
• security_analyzer — using LLMSecurityAnalyzer()

Both should be optional and configurable through EvalMetadata fields.

Context

This was previously tracked as a TODO comment in the codebase (removed in #440). Creating this issue to properly track the work.

# condenser=get_default_condenser(
#     llm=self.metadata.llm.model_copy(update={"service_id": "condenser"})
# ),
# security_analyzer=LLMSecurityAnalyzer(),

@simonrosenberg I'm working on the condenser here #429
So maybe this issue could be only for security analyzer.
