fix: Add editor.view null checks to prevent click errors

Added defensive checks for editor.view across editor components to prevent
"Cannot read properties of undefined (reading 'posAtCoords')" errors when
clicking before editor is fully initialized.

Fixed in:
- focusEditor utility function
- ComposerLinkManager dropdown handlers
- bubble-menu event listeners and shouldShow
- SearchAndReplace goToSelection
