Merge multiscreen webview fix into latest main - Support for multiscreen configuration for WebView display

Note(Amadeo): related to #152

This fixes Bug 152, and is based on the latest main. It also contains text resources. There are some layout improvements I plan to fix, but I try to avoid a running away code base, thus early checkin/merge.

nice one, targeting current main should make it quite easy to target 2.2.0-beta1 (that this will end up in :D) - you can even change the target from main to https://github.com/hass-agent/HASS.Agent/tree/development-2.2.0-beta1
give me a day or two to review pls :)

While testing, I found on one specific dual-screen setup a layout issue, the WebView would not show at bottom right on the second screen. Will look into that to fix it soon too.

@amadeo-alex - i just added a fix for multi-screen form bottom right positioning. Seems to make sense and is tested. PR ready for review I would say :-)
