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)

+# Translations
+
+## Requirements
+
+- Install [LibreOffice Calc](https://libreoffice.org/)
+- Ensure you have Python 3 installed (Python 2 is not supported)
+
+## Steps
+
+To add new translations or edit existing ones, please follow these steps:
+
+1. Edit `Translations.ods` (see chapter below)
+2. In LibreOffice Calc, select the relevant tab that you want to export
+3. Click on `File` -> `Save a copy...` and save the file as `[tabname].csv` (without the "[]")
+4. Repeat step 2 and 3 for all tabs that you updated
+5. Run `python generate-all.py`
+
+## Notes
+
+- Do not commit the CSV files
+- When editing the ODS file, make sure you don't paste in formatted data (use CTRL+Shift+V instead of CTRL+V)
+- ODS export settings:
+    - Field delimiter: `,`
+    - String delimiter: `"`
+    - Encoding: `UTF-8`
