Use monospace font for some settings in admin UI

[tdilauro]

Description

Enable monospace font rendering for form fields in the OIDC and SAML patron authentication configuration models that contain code-like content — regular expressions, filter expressions, JSON, and XML/PEM blobs.

Motivation and Context

Fields holding structured or code-like values (regex patterns, Python expressions, XML metadata, JSON objects, private keys) are easier to read and edit in a monospace font. This sets use_monospace_font=True on those fields in the admin UI so their content renders as expected.

How Has This Been Tested?

• Manual testing in local dev environment to verify that fields display with correct font family.
• No logic changes, so existing tests should continue to pass.

Checklist

• N/A - I have updated the documentation accordingly.
• N/A - All new and existing tests passed.

Code Review

• Read PR diff and changed files
• Verify use_monospace_font is a valid, correctly-serialized flag
• Check that flagged fields are all code-like
• Check for missed / inconsistent fields

Summary

This is a clean, low-risk, purely additive change. Each of the 11 additions sets use_monospace_font=True on a form field whose value is genuinely code-like — regex patterns, Python filter expressions (TEXTAREA), JSON blobs (extra_data), and XML/PEM material (service_provider_xml_metadata, service_provider_private_key, non_federated_identity_provider_xml_metadata). The flag is a well-supported hint on FormMetadata (defaults to False, serialized in to_dict at src/palace/manager/integration/settings.py:187-188), and its behavior is already covered generically in tests/manager/integration/test_settings.py, so no new tests are warranted for what is effectively a per-field UI hint. I also checked for consistency: the only TEXTAREA field left without the flag is OIDC auth_link_description (model.py:411-423), which holds patron-facing prose ("Log in with your university credentials") rather than code — correctly excluded. All Pattern/JSON/code-bearing TEXTAREA fields in both models are covered. No issues found.

Greptile Summary

This PR adds monospace rendering hints to code-like patron authentication settings.

• OIDC regex, filter expression, and JSON fields now request monospace display.
• SAML XML, PEM, regex, filter expression, and JSON fields now request monospace display.
• Library-level filter expression fields now use the same display hint.

Confidence Score: 5/5

This looks safe to merge.

• No blocking issues found in the changed code.
