fix(omny): fix stale widget-API bugs in gui_tools.py cameras/xray-eye, add cam_xeye

Live testing of the previous gui_tools.py port (49ade7c) hit two further crashes:

1. omnygui_show_xeyealign() -> ValueError: Device 'cam_xeye' not found in current
   BEC session. The OMNY_XRayEye widget (shared verbatim with flomni) hardcodes
   CAMERA = ("cam_xeye", "image") as a module constant -- it isn't configurable
   per-beamline, so omny needs its own cam_xeye device or the widget can never be
   constructed. Added cam_xeye to simulated_omny.yaml (hand-added, duplicating
   flomni's real cam_xeye's camera_id/pixel_calibration as placeholders; SimIDSCamera
   already accepts both camera_id and the legacy camera_ID key omny's other cameras
   use). ptycho_omny.yaml intentionally left untouched -- the real hardware camera ID
   and pixel calibration for OMNY's x-ray-eye camera are unknown; noted as a followup
   in OPEN_ISSUES.md, including that a future regen of simulated_omny.yaml from
   ptycho_omny.yaml will drop this hand-added block until the real config has one too.

2. omnygui_show_omnycam_parking() -> ValueError: Unknown widget type: BECImageWidget.
   That string was carried over unmodified from omny's pre-modernization code, not
   from flomni's current gui_tools.py (whose current class name is "Image"). Beyond
   the widget name, the per-camera calls inside were also stale: fig.set_rotation(
   deg_90=3) doesn't exist on the current Image/ImageBase widget at all (replaced by
   the num_rotation_90 property), and self.figN.lock_aspect_ratio(True) called a
   property as a function. Ported omnygui_show_omnycam_parking()/
   omnygui_show_omnycam_samplestage() onto flomni's current per-camera pattern
   (image(device=, signal="preview"), num_rotation_90/lock_aspect_ratio as
   properties, start_live_mode()), preserving the existing 3x90 rotation for
   cam200/cam203 (physical mount) and no rotation for cam201/cam202, unchanged from
   before.

Also removed omnygui_show_cameras() (added last pass, modeled on flomni's single
generic camera view): redundant now that both existing parking/samplestage views got
the current API, since omny -- unlike flomni -- already has two purpose-built camera
views. Its hard-stop console (z_ConsoleButtonsWidget, targeting otransy) now lives
directly in both omnygui_show_omnycam_parking() and omnygui_show_omnycam_samplestage()
instead.

 `omny_webpage_generator.py` already reads the ETA-ish fields defensively via `.get()`, degrading
 to "N/A" when absent, and that file is unwired/dead code anyway (see below).
 
+## cam_xeye device (simulated only, real hardware config still needed)
+
+`omnygui_show_xeyealign()` uses the shared `OMNY_XRayEye` widget
+(`csaxs_bec/bec_widgets/widgets/xray_eye/x_ray_eye.py`), which hardcodes `CAMERA = ("cam_xeye",
+"image")` as a module-level constant -- the device name isn't configurable per-beamline. omny's
+config had no `cam_xeye` device at all, so simply calling `omnygui_show_xeyealign()` failed with
+`ValueError: Device 'cam_xeye' not found in current BEC session` as soon as the widget was
+constructed. Added a `cam_xeye` entry to `simulated_omny.yaml` (hand-added, not generated --
+`ptycho_omny.yaml`, the generator's source, has no such device), reusing flomni's real `cam_xeye`'s
+`camera_id`/`pixel_calibration` as placeholders (`SimIDSCamera` accepts both `camera_id` and the
+legacy `camera_ID` key omny's other sim cameras use). **Two follow-ups still needed before real
+hardware use:**
+- `ptycho_omny.yaml` needs a real `cam_xeye` entry with OMNY's actual x-ray-eye camera hardware
+  `camera_id` and measured `pixel_calibration` (mm/pixel) -- unknown to me, needs Mirko.
+- `simulated_omny.yaml` is regenerated by `bin/generate_simulated_configs.py` from
+  `ptycho_omny.yaml`; since `cam_xeye` isn't in the real config yet, a regen will drop this
+  hand-added block until the real config also has one (matches the existing pattern for
+  `sim_velocity`/`sim_initial_position` hand-additions elsewhere in this file, already present
+  before this session).
