Half Decent Scale firmware v3.1.12

This release finalizes the HDS sleep/wake, ADS1232 startup, and calibration fixes tested in the v3.1.12-preview.1 and v3.1.12-preview.2 builds.

Fixed a problem where the scale could show stuck 0g readings after waking from sleep.
Improved wake-up behavior so the scale starts weighing normally again after Sleep or Soft Sleep.
Improved startup zeroing so the scale waits for wake buttons to be released before doing its boot tare.
Improved load-cell startup handling for more reliable readings after boot and wake.
Improved calibration handling, including support for signed calibration values.
Calibration no longer gets blocked just because USB is attached. The scale now shows a short warning, then lets you continue.
Reduced confusing shutdown error messages when WiFi was already off.
Includes the web app and firmware cleanup already tested in the preview builds, with no intended BLE, USB, WebSocket, or web app protocol changes.

HDS now uses the hardened decentespresso/ADS1232_ADC driver from decentespresso/ADS1232_ADC.
The final firmware pins ADS1232 to commit 24cd10d3037c878f751a057377303598a00f977e.
That commit is based on the preview.2 ADS hardening commit 08e3a6bf03722f467a2f8a76d88111923bd55477.
The ADS hardening includes polling, startup, wake, timeout, lifecycle, diagnostics, raw sample, and tare handling improvements.
Soft Sleep wake now powers ADS back up, refreshes the ADS dataset, and resumes weighing without auto-taring.
Boot tare now uses a boot-only fresh tare after startup input/menu conditions are safe, instead of the old scale.start(..., true) startup tare.
Calibration accepts signed calibration factors where valid.
