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)

 - Move Development settings from flash to `/data/apps/development/development.properties` (just the "start on boot")
 - Move Display settings from flash to `/data/apps/display/display.properties`
-- App data directory should be automatically created (and then we can remove the custom code from Notes.cpp)
-- When an external app fails to load (e.g. due to mapping error) then show an error dialog.
 - Expose app::Paths to TactilityC
 - Call tt::lvgl::isSyncSet after HAL init and show an error (and crash?) when it is not set.
 - External app loading: Check the version of Tactility and check ESP target hardware to check for compatibility.
-- Localization of texts (load in boot app from sd?)
 - App packaging
 - Create more unit tests for `tactility-core`
 - Make a URL handler. Use it for handling local files. Match file types with apps.
+- Fix Development service: when no SD card is present, the app fails to install. Consider installing to `/data`
+- Refactor `PropertiesFile.cpp` to use `tt::file::readLines()` (see TODO in code)
+- Localize all apps
