Merge develop into main (#339)

- Update ILI9341 driver to v2.0.1
- Lots of code cleanup for apps
- Refactor app "type" into "category" and added flags to the manifest (for show/hide statusbar and for hidden apps)
- Rename some ElfApp-related functionality and improved the way the static data was managed
- Rename "filebrowser" to "files"
- Added cstring functions to tt_init.cpp
- Minor fix in Boot app
- Updated external apps for SDK changes

 ## Higher Priority
 
 - Show a warning in the web installer when flashing CYD 28R board regarding v1/v2/v3
-- Fix Development service: when no SD card is present, the app fails to install. Consider installing to `/data`
-  Note: Change app install to "transfer file" functionality. We can have a proper install when we have app packaging.
-  Note: Consider installation path option in interface
 - External app loading: Check the version of Tactility and check ESP target hardware to check for compatibility.
 - Make a URL handler. Use it for handling local files. Match file types with apps.
   Create some kind of "intent" handler like on Android.
   The intent can have an action (e.g. view), a URL and an optional bundle.
   The manifest can provide the intent handler
-- Update ILI934x to v2.0.1
-- Apps with update timer in onCreate() should check `lvgl::isStarted()`
 - CrowPanel Basic 3.5": check why GraphicsDemo fails
 - CrowPanel Basic 3.5": check why System Info doesn't show storage info
-- Update to LVGL v9.3 stable
+- When an SD card is detected, check if it has been initialized and assigned as data partition.
-- Create `app::getSettingsPath()` to get paths to properties files by first trying sd card and then trying `/data`
+  If the user choses to select it, then copy files from /data over to it.
+  Write the user choice to a file on the card.
+  File contains 3 statuses: ignore, data, .. initdata?
+  The latter is used for auto-selecting it as data partition.
