Handle Errors in wifiConfigstore2 and gboard

[AspHyxia28]

Fix: Gracefully handle errors in wifiConfigstore2 and gboard parsers

Summary

Improves robustness of artifact parsers by adding proper error handling for missing data and corrupted files.

Changes

wifiConfigstore2.py

• Initialize all 14 data variables to empty strings before XML processing
• Prevents UnboundLocalError when XML fields are missing from the data structure
• Allows parser to complete successfully with incomplete WiFi configuration data

gboard.py

• Import DecodeError from google.protobuf.message
• Wrap protobuf decoding logic in try-except block to catch and skip malformed data
• Skip individual rows with corrupted protobuf messages instead of crashing entire artifact
• Log skipped rows for debugging and transparency

Testing

Both parsers now complete successfully when encountering:

• Missing or incomplete data fields
• Corrupted protobuf messages
• Malformed file structures

Valid data is still extracted and reported, with errors logged appropriately.
