fix: Recreate one-shot install script with APT permission and non-interactive fixes
Recreate one-shot install script that was deleted, with fixes for: 1. APT permission denied errors on /tmp 2. Non-interactive mode support Fixes: 1. Fix /tmp permissions before running first_time_install.sh: - chmod 1777 /tmp to ensure APT can write temp files - Set TMPDIR=/tmp explicitly - Preserve TMPDIR when using sudo -E 2. Enable non-interactive mode: - Pass -y flag or LEDMATRIX_ASSUME_YES=1 to first_time_install.sh - Prevents read prompt failure at line 242 when run via curl | bash 3. Better error handling: - Temporarily disable errexit to capture exit code - Re-enable errexit after capturing - Added fix_tmp_permissions() function This resolves the 'Permission denied' errors for APT temp files and the interactive prompt failure when running via pipe.
