Refactor font handling and theme config, switch to CodeMirror editor

Replaces Monaco editor with CodeMirror in the frontend, removing related dependencies and configuration. Refactors font management to support multiple formats (woff, woff2, ttf, otf) and dynamic font switching, including backend API and frontend theme config UI. Adds gzip compression middleware to backend. Updates theme config to allow font selection and custom font upload, and improves theme preview and color customization UI. Cleans up unused code and improves sidebar and terminal font sizing responsiveness.
