Spring cleaning

With the help of our community, we identified and fixed bugs that were making Indy a little hard to use:

Fixed resending and sharing of documents
Fixed invoice email previews so that they are correctly displaying deposits
Addressed an invoice payment issue with shared invoice links
Some documents weren't displaying the most up-to-date information when navigating between pages. Now they are.
Uploaded video files are rendering and previewing correctly again
Improved how the Digital Assistant works so that the results are more accurate.
