Merge develop to main (#334)

- `FileBrowser` app now supports deleting directories (recursively)
- `DevelopmentService` and `tactility.py` now support the app `uninstall` action
- Fix crash for `File` app: implement file locking in several places (SPI SD cards need it)
- Remove I2C configuration from `M5stackCardputer.cpp` because we don't support the "Cardputer Adv" variant in that firmware.
