Add Craft mode — direct satellite tracking via space.warehack.ing API

New F2 Control sub-mode that searches the Craft orbital catalog (22k+
objects), displays pass predictions, and drives the dish in real-time
using server-computed AZ/EL positions from /api/sky/up.

Tracking loop polls at ~1Hz, filters for the tracked target by
target_type + target_id (str, not int — handles satellites, planets,
stars, comets), and issues motor commands through the existing serial
bridge. Verified end-to-end with Carryout G2 hardware tracking NOAA 17.

New files:
- craft_client.py — stdlib HTTP client (urllib only, no deps)
- widgets/craft_panel.py — search table, pass info, tracking status
- tests/test_craft_mode.py — 5 unit tests with mocked API
- tests/test_craft_integration.py — 3 hardware integration tests
