fix(UI-1775): refactor code editor to solve syntax highlight bug (#1299)

## Description
## Summary

**Fix:** Correct Python syntax highlighting (incl. f-strings) in Monaco.
**Approach:** Integrate TextMate grammar using monaco-editor-textmate +
onigasm.

**Context**
Python strings/f-strings were tokenized incorrectly, producing broken
highlighting.
Addresses UI-1775 by wiring a proper Python TextMate grammar.

**Changes**
**Editor integration:** Loads TextMate grammar only for Python files;
editor stays read-only until grammar init completes and shows a short
loader.

Binary asset: Adds a WASM file;
Performance: One-time load on first Python editor mount; then
browser-cached.
