fix(ui): adjust docx and code rendering (#4334)

* fix(ui): adjust docx and code rendering

* fix(ui): address PR feedback on docx fit and Monaco type cast

Use computed padding from `.docx-wrapper` instead of a hardcoded 60px
so the fit calculation survives docx-preview library changes. Replace
the inline `import()` cast for ShowLightbulbIconMode with a top-level
type import.
