chore: Rename file utility functions with cloudsync prefix

Renamed file_delete, file_read, and file_write (and related static helpers) to cloudsync_file_delete, cloudsync_file_read, and cloudsync_file_write for improved clarity and namespace consistency. Updated all usages in cloudsync.c and utils.c/h accordingly.
