Fix function naming: anonmyze → anonymize, input → value

[Copilot]

Addresses review feedback on the anonmyze helper function introduced in #113.

Changes:

• Corrected function name from anonmyze to anonymize
• Renamed parameter input to value to avoid shadowing Python's built-in input() function
• Updated all 7 call sites

Before:

def anonmyze(input, uci: EUci):
    if fact_subscription_status(uci).get('status', 'no') != "no":
        return input
    h = hashlib.sha1(input.encode()).hexdigest()
    return f"anon-{h[:16]}"

After:

def anonymize(value, uci: EUci):
    if fact_subscription_status(uci).get('status', 'no') != "no":
        return value
    h = hashlib.sha1(value.encode()).hexdigest()
    return f"anon-{h[:16]}"
