Config: streamline config structure and reorganize modules

- Remove init-workspace.el and redundant UI/font/autothemer setup
- Add init-prog.el for programming language configs (treesit, lua, scheme, etc.)
- Defer org-refile loading via org-mode hook
- Adjust load order in init.el, add init-proxy
- Fix indentation and formatting issues
