fix: FTP storage backend, SD info display, time label alignment

Browse Source 
- Fix FTP using FFAT instead of SD_MMC: define both NETWORK_TYPE (6) and
  STORAGE_TYPE (10) with numeric values to bypass FtpServerKey.h guard
- Fix SD capacity showing 'f/f GB': use integer math instead of floats
  (LVGL builtin sprintf lacks %f support)
- Fix time/date labels tilting 45°: set fixed width + LV_TEXT_ALIGN_CENTER
- Switch LVGL sprintf to C stdlib for future float compatibility
