[Code scan] Search all OUT directories before average_pot exits

[njzjz]

This issue is a result of a Codex global repository scan.

aveElecStatPot.py exits as soon as it sees the first OUT.* directory without ElecStaticPot.cube, even if a later OUT.* directory contains the file. If no root-level cube and no matching OUT.* cube are found, the script can also fall through to open(input_file) with input_file undefined.

	dir_path = os.path.join(current_dir, dir_name)

Relevant code:

for dir_name in os.listdir(current_dir):
    dir_path = os.path.join(current_dir, dir_name)

    if os.path.isdir(dir_path) and dir_name.startswith("OUT."):
        input_file = os.path.join(dir_path, "ElecStaticPot.cube")
        ...
        if os.path.exists(input_file):
            break
        else:
            print(f"File does not exist: {input_file}")
            sys.exit()
                        
with open(input_file, 'r') as inpt:

Suggested fix:

Scan all candidate locations first, select the first existing ElecStaticPot.cube, and emit one clear error after the loop if no cube was found.
