webui: replace hardcoded Monaco language map with dynamic detection

Replace the static language mapping in the Monaco diff editor with
Monaco's built-in language registry for automatic language detection.

Changes:
1. Remove hardcoded langMap that only supported 8 languages (js, ts, py,
   html, css, json, md, go)
2. Implement dynamic language detection using monaco.languages.getLanguages()
3. Cache language list for performance since it doesn't change at runtime
4. Maintain exact extension matching including the dot prefix (.js, .ts, etc.)
5. Preserve fallback to 'plaintext' for unknown extensions

Benefits:
- Automatically supports all languages Monaco knows about (40+ languages)
- No maintenance burden when Monaco adds new language support
- Removes duplication between Monaco's registry and our hardcoded map
- Better future-proofing as Monaco language support evolves

The implementation uses Monaco's ILanguageExtensionPoint interface which
provides language.extensions arrays for each registered language. This
is more reliable than maintaining our own mapping and ensures consistency
with Monaco's actual language support.
