Use monospace font for some settings in admin UI (#3546)

## 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.
