feat(files-editor): mount auto-language editor + dropdown override

Browse source 
The modal textarea opts in with data-editor-language=auto; the editor
derives the language from the filename extension on each modal open.
A dropdown lets the user override (srccfg / bash / plain). The
existing fetch-based /files/save path is unchanged — files-overlay.js
keeps reading textarea.value, which the editor mirrors.
