Merge develop into main (#305)

## New features

- Implement translations for apps
- Created `tt::settings::setLanguage` and `::getLanguage()`
- External app errors are now reported to the user via an AlertDialog
- Store system settings in `/data/settings.properties`
- Created a "Region & Language" app and moved the timezone setting there.

## Other changes

- Change `/data` and `/system` filesystem sector size from 4096 to 512 bytes to allow for more small files (60+ files of 4kB were over the limit of 256kB for the filesystem)
- Increased size of `/data` and `/system`
- Moved `tt::time::*` to `tt::settings`
- Removed the timezone setting from the "Time & Date" setting app
- Reverse encoder direction of Lilygo T-Lora Pager
- Improved partability of `Time.cpp` (removed separate set of functions for PC/sim)
