Fix all ((configured_count++)) instances causing script exit during configuration

- Replace ((configured_count++)) with configured_count=$((configured_count + 1))
- This fixes script exiting prematurely after configuring first application
- Issue: ((var++)) returns old value (0) which causes exit with set -euo pipefail
- Fixed 14 instances across the configure_applications_for_tmpfs function
