Fix HA switch badge toggle and multi-plug crash

  Non-script HA entities (switch/light/input_boolean) on the printer card
  always sent turn_on when clicked, which is a no-op when the switch is
  already on. Now sends toggle for non-script entities so the badge click
  actually changes the switch state. Script entities still use turn_on.

  Also fix SmartPlugManager._get_plug_for_printer() using
  scalar_one_or_none() which crashes with MultipleResultsFound when
  multiple plugs are assigned to the same printer (e.g., Tasmota + HA
  switch). Now fetches all plugs and returns the main non-script plug.

  Add tests for both fixes: _get_plug_for_printer multi-plug handling
  (5 tests) and canonicalFilamentType/filamentTypesCompatible/autoMatch
  PA-CF equivalence (8 tests).

@@ -35,6 +35,8 @@ All notable changes to Bambuddy will be documented in this file.
 - **iOS/iPadOS Cannot Reposition Floating Camera** ([#687](https://github.com/maziggy/bambuddy/issues/687)) — The floating camera viewer (embedded camera window on the dashboard) could not be dragged or resized on iOS/iPadOS because it only handled mouse events. Touch input scrolled the page underneath instead of moving the camera window. Added touch event support (`touchstart`/`touchmove`/`touchend`) to both the header drag handle and the resize handle, with `preventDefault` to stop page scrolling during drag. Reported by @dsmitty166.
 - **PA-CF / PA12-CF / PAHT-CF Not Treated as Compatible** ([#688](https://github.com/maziggy/bambuddy/issues/688)) — Bambu Lab firmware treats PA-CF, PA12-CF, and PAHT-CF as interchangeable, but the print scheduler and filament override UI used exact string matching. If a 3MF required PA-CF but the AMS had PA12-CF loaded, the scheduler wouldn't assign the job and the filament override dropdown was empty/disabled. Added a filament type equivalence system so these PA variants are treated as compatible in scheduler assignment, AMS slot matching, force color match validation, and the filament override dropdown. Reported by @aneopsy.
 - **Force Color Match Toggle Click Target Too Large** ([#688](https://github.com/maziggy/bambuddy/issues/688)) — In the Schedule Print modal, clicking anywhere on the "Force color match" row toggled the checkbox, not just the checkbox and its label. The click target now covers only the checkbox, icon, and label text. Reported by @aneopsy.
+- **HA Switch Badge Always Sends Turn On Instead of Toggle** — Clicking a non-script Home Assistant entity (switch, light, input_boolean) on the printer card always sent `turn_on`, which is a no-op when the switch is already on. Now sends `toggle` for non-script entities so the badge click actually toggles the switch state. Script entities still use `turn_on` (stateless trigger).
+- **Multiple Plugs Per Printer Crashes Auto-On/Off** — When multiple smart plugs were assigned to the same printer (e.g., a Tasmota plug + an HA switch), the auto-on/auto-off handler called `scalar_one_or_none()` which raises `MultipleResultsFound`. Now fetches all plugs and returns the main (non-script) power plug, matching the API route behavior.
 - **Debug Logging Endpoint 500 Error** — The `GET /api/v1/support/debug-logging` endpoint returned a 500 Internal Server Error when the database contained a timezone-aware timestamp written by a previous version. The duration calculation subtracted a timezone-aware datetime from a naive `datetime.now()`, raising `TypeError`. Now strips timezone info when reading the stored timestamp.
 - **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.
