feat: add word wrap support to CodeMirror editors

Implements lineWrapping: true configuration for all CodeMirror editor instances in the admin UI:
- Main editor configs (headers, schema, resource content, prompt template, etc.)
- Gateway test editors (headers and body)

This improves readability for long lines of text/code, particularly helpful for JSON content and long string values, eliminating horizontal scrolling in the admin panel editors.

Fixes #570
