Add Craft mode and Camera sections to TUI guide

Document the F2 Craft sub-mode (search, passes, 1 Hz tracking via
space.warehack.ing API) and F6 Camera overlay (manual, interval, and
pass-event triggers). Update screen count from five to six, add
satellite catalog to demo mode bullet list, remove orphaned
tui-position.png screenshot.

+Craft mode connects directly to the [space.warehack.ing](https://space.warehack.ing) API for
+satellite and celestial body tracking — no rotctld server, no external controller. Type a name
+in the search bar and the catalog returns matches with NORAD ID, type, and group. Select a
+target from the results table, then hit **Track** to start following it at 1 Hz.

+
+The status panel shows the tracking lifecycle: **IDLE** (nothing selected), **TRACKING** (target
+above minimum elevation, dish is moving), or **WAITING** (target below the minimum elevation
+floor — the dish holds position until the target rises). Sat AZ and Sat EL update each second
+with the target's computed position. The **Passes** button fetches upcoming pass predictions
+for LEO targets — rise time, peak elevation, and duration.
+
+Pass state transitions (WAITING → TRACKING at AOS, TRACKING → WAITING at LOS) feed into the
+Camera overlay's automatic trigger system, so you can capture images at acquisition of signal,
+closest approach, or loss of signal without manual intervention.

+Three trigger modes:

+- **Manual** — press **c** to capture a single frame on demand
+- **Interval** — set a timer and capture automatically at a fixed cadence
+- **Pass events** — fire on AOS (acquisition of signal), TCA (time of closest approach),
+  or LOS (loss of signal) transitions from the Craft or Track tracking loops
+
+Each capture produces a JPEG frame paired with a JSON sidecar containing dish position,

+time, output formats, and which triggers are armed.
