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.
