USB-C charging now shows on M1 Pro and M1 Max MacBook Pros

Two solid fixes this time. If you have an M1 Pro or M1 Max MacBook Pro, WhatCable finally shows your USB-C charger: macOS never publishes the per-port power data on that generation, so the app now derives it from the battery controller instead. And Saved Cables got a durability overhaul, so your cable collection and its recorded history are written to disk far more robustly.

Fixed

• USB-C charging on M1 Pro and M1 Max MacBook Pros. These Macs never publish the per-port power source that the charging display reads (0 of 61 machines in our community data), so a USB-C charger showed nothing at all. WhatCable now reconstructs the charge contract from the battery controller's own per-port data, on any MacBook where the usual source is missing. Desktop Macs are unaffected. Thanks @grtm77 for the report (#401).
• Saved cables and their history are now much harder to lose. Every change to your saved cables is written straight into the main database file, and recorded history is flushed on quit. Previously everything could sit indefinitely in a sidecar file that backup and cleanup tools sometimes mishandle, and a damaged database could silently reset to empty. It now refuses to touch your data rather than guess, and logs what happened so we can diagnose any report.

Improved

• Italian translation refreshed. Thanks @bovirus.
• Traditional Chinese translation refreshed. Thanks @jimmyorz.
