fix(modal): correct vim insert mode activation in task creation modal (#1410)

The 4.2.0 implementation used an incorrect path to access the CodeMirror
vim adapter. This fix:
- Uses correct path (editor.cm.cm) to access the CM5 adapter
- Adds fallback to activeCM for compatibility
- Adds 50ms delay to ensure vim extension has initialized

Thanks to @Leo310 for the feature request and testing.
