Technician tool v0.7 - changes

Serial reading (firmware 1.0.16+, see firmware-diagnostics-what-changed.md)

KOTA: <record> key=value lines are parsed into fields (core/logline.py, kind KOTA) and interpreted directly by the engine (diag/engine.py _kota_*, knowledge in diag/kota.py) instead of regex rules: boot, i2c, rtc, sd, matter, mic, health, status, led, restart.
Exact status LED (colour + pattern + meaning) from led lines; status lines give the reason and a status finding that is resolved when the status changes. Cyan LED supported.
Restart cause from last_restart= / restart reason=; state before a restart from led previous_boot.
Error IDs [E-XX-NN]: looked up in diag/error_ids.csv (copy of the firmware's docs/error_ids.csv); shown with the technician action. Old message rules still match (ID prefix is stripped for matching).
Diagnosis panel: new "Box self-report" section; log view filter "KOTA diagnostics + errors".
Matter QR dialog uses the exact QR/manual code reported by the box.
Older firmware (v1.0) is still diagnosed as before.

Only .bin files in the tool's firmware/ folder can be flashed (import / developer library removed, no manifest needed). The list shows the compile date read from the firmware itself, newest first.
"Refresh list" and "Open firmware folder" buttons; broken or duplicate files are listed as "Not offered".
Flash verification compares the 8-digit build hash from the KOTA: boot line.

Note: the KOTA lines are tested against lines built from the firmware source; the firmware has not yet been confirmed on hardware.
