Ashtin 2a4198c2c8 Sanitize device fields and prevent crash with numeric hostnames ...

This patch improves the resilience of the guess_icon function by sanitizing mac, vendor, and name fields to avoid crashes caused by unexpected data types (e.g., numeric hostnames).

Specifically:

mac is now cast to a string before being uppercased, with a newly added fallback to "00:00:00:00:00:00" if empty or invalid.

vendor is sanitized to a string before lowercasing, still defaulting to "unknown".

name is cast to a string before lowercasing, still falling back to "(unknown)" when empty.

This change not only resolves the error caused by numeric-only hostnames (which triggered an AttributeError due to calling .lower() on an int), but also proactively prevents similar crashes from malformed or unexpected input in the future.

References: Fixes issue #1088 and also let's me sleep a little easier tonight.
