feat(devices): DeviceModel::V2 for Waveshare 13.3" Spectra-6

Adds the second panel model alongside V1 (800x480, 7.3"). V2 is
1200x1600 panel-native (tall) — the inverse aspect ratio means
its "natural" orientation is portrait, not landscape:
- DeviceModel::nativeOrientation() — V1 returns Landscape, V2 returns
  Portrait. Render rotates the source image 90 CCW only when the user's
  orientation differs from the panel's native, so the .bin stays
  panel-native scan order without per-model branches.
- DeviceModel::panelId() / fromPanelId() — string mapping for the
  firmware's X-Panel-Id header (matches -DPANEL_ID build flag).
- DeviceImageController: on every poll, if X-Panel-Id maps to a known
  model and differs from the device's current model, auto-correct.
  New Devices are created with the V1 default, so a freshly-claimed
  13.3" unit needs this correction before the first image render
  produces a wrong-dimension .bin the firmware would reject.

8 new DeviceModel unit tests, 3 new controller tests cover the
header-correction behaviour (different, same, unknown panel-id).
