This improves error messages throughout. It might sometimes be too verbose, but that's better than being opaque (#74).
Also upgrades Deno's patch version.
Fixes#74
This implements the option to choose directories when uploading files via the Web UI (The most important part of #52).
When you choose a directory, its file and sub-directory structure will be maintained.
Tested with the latest Safari, Firefox, and Chrome.
Additionally, the Deno version was updated, which required some accessibility improvements as well.
Additionally:
- Make expense and budget modal "reset" once closed, saved, or deleted.
- Make manifest icons dark
- Budgets in small screens should be full-screen
- Minor code cleanup
Fixes#48
