Fix ethernet badge shown on WiFi-only printers (#585)

    home_flag bit 18 is set on all printers regardless of hardware,
    causing the ethernet badge to appear on WiFi-only models (A1, P1P,
    etc.). The previous fix removed the feature entirely, so ethernet
    printers lost their badge too.

    Now only trusts bit 18 on models with an ethernet port (X1C, X1E,
    P1S, P2S, H2D, H2D Pro, H2C, H2S). WiFi-only models always show
    the WiFi signal badge.

@@ -28,7 +28,7 @@ All notable changes to Bambuddy will be documented in this file.
 - **Bed Cooled Notification Never Fires** ([#497](https://github.com/maziggy/bambuddy/issues/497)) — The bed cooldown monitor always timed out after 30 minutes without sending a notification. After print completion, P1S (and likely other models) sends partial MQTT status updates that don't include `bed_temper`, so the cached bed temperature stayed frozen at the end-of-print value and never dropped below the threshold. The monitor now sends periodic `pushall` commands to the printer to force fresh temperature data. Also added debug logging to the polling loop for future diagnostics.
 - **Notification Provider Missing Event Toggles on Create** ([#497](https://github.com/maziggy/bambuddy/issues/497)) — When creating a new notification provider, the `on_bed_cooled` toggle and all 7 queue event toggles (`on_queue_job_added`, `on_queue_job_assigned`, `on_queue_job_started`, `on_queue_job_waiting`, `on_queue_job_skipped`, `on_queue_job_failed`, `on_queue_completed`) were silently discarded. The create endpoint manually listed each field but omitted these 8 toggles, so they always defaulted to `false` regardless of user selection. Editing an existing provider worked correctly.
 - **Clear Plate Prompt Shown for Staged Queue Items** — The "Clear Plate & Start Next" button on the printer card appeared when all pending queue items were staged (`manual_start`/Queue Only), even though the scheduler won't auto-start them. The clear plate prompt now only appears when there are auto-dispatchable items that the scheduler will actually start after the plate is cleared.
-- **Ethernet Badge Always Shown on Printer Cards** — The printer card network badge always showed "Ethernet" instead of the WiFi signal indicator, even on printers without an ethernet port. The `home_flag` bit 18 was incorrectly interpreted as indicating a wired connection. Removed the faulty ethernet detection; the WiFi signal badge now displays correctly when the printer reports signal strength.
+- **Ethernet Badge Shown on WiFi-Only Printers** ([#585](https://github.com/maziggy/bambuddy/issues/585)) — The ethernet badge was shown on all printer models, including WiFi-only models like A1 and P1P that don't have an ethernet port. The `home_flag` bit 18 is set on all printers regardless of hardware. Now only parses the ethernet flag on models that actually have an ethernet port (X1C, X1E, P1S, P2S, H2D, H2D Pro, H2C, H2S). Printers connected via ethernet show an "Ethernet" badge; all others show the WiFi signal indicator.
 - **GitHub Backup Required Cloud Login** ([#655](https://github.com/maziggy/bambuddy/issues/655)) — The GitHub backup settings card was completely blocked behind Bambu Cloud authentication, showing "Bambu Cloud login required" even though the backup feature works without it (K-profiles and app settings don't need cloud). Removed the cloud auth gate so GitHub backup can be configured and used without Bambu Cloud. The "Cloud Profiles" checkbox is disabled with a hint when not logged in. Reported by @TravisWilder.
 - **GitHub Backup Log Timestamps Off by 1 Hour** — Backup log timestamps in the history table were displayed in UTC instead of the user's local timezone. The local `formatDateTime` function didn't use `parseUTCDate`, so timezone-less timestamps from SQLite were interpreted as local time. Now uses the shared `parseUTCDate` utility for correct UTC-to-local conversion.
 - **H2D AMS Units Shown on Wrong Nozzle** ([#659](https://github.com/maziggy/bambuddy/issues/659)) — On the H2D dual-nozzle printer, AMS units were displayed on the wrong nozzle (e.g. both AMS-HT and AMS2 Pro shown on the left nozzle instead of their correct assignments). Three interrelated bugs in the AMS `info` field parsing: (1) the field was parsed as decimal instead of hexadecimal (BambuStudio uses `std::stoull(str, nullptr, 16)`), (2) the extruder ID was extracted as a single bit instead of a 4-bit field, and (3) partial MQTT updates overwrote the full extruder map instead of merging. Now correctly hex-parses the `info` field, extracts the 4-bit extruder ID from bits 8-11, skips uninitialized AMS units (`0xE`), and merges partial updates into the existing map. Reported by @cadtoolbox.
