Better scope fallback for Node/global/window

Manually implemented a better fallback from PR #134
This is intended to help with running in non-browser environments like Node and Vite.
Bumped dev-time packages.
Also moved the ensureSandboxWindow method out one layer in preparation for upcoming PR #135 for pruning.

 The 3.x release branch included some breaking changes in the vary infrequently used ability to configure some utility methods used in this internal processing of dom-to-image-more. As browsers have matured, many of the hacks we're accumulated over the years are not needed, or better ways have been found to handle some edge-cases. With the help of folks like @meche-gh, in #99 we're stripping out the following members:
 
--   `.mimes` - was the not-very-comprehensive list of mime types used to handle inlining things
--   `.parseExtension` - was a method to extract the extension from a filename, used to guess mime types
--   `.mimeType` - was a method to map file extensions to mime types
--   `.dataAsUrl` - was a method to reassemble a `data:` URI from a Base64 representation and mime type

 The 3.x release branch should also fix more node compatibility and `iframe` issues.

 ### Tests
 
 As of this v3 branch chain, the testing jig is taking advantage of the `onclone` hook to insert the clone-output into the testing page. This should make it a tiny bit easier to track down where exactly the inlining of CSS styles against the DOM nodes is wrong.
