Dynamic layout for WiFi setup: landscape rotation, responsive render, highlight feedback

- Render functions use axs15231b_get_width/height() instead of hardcoded coords
- render_wifi_setup_list: dynamic item widths, screen-relative cancel button
- render_wifi_setup_password: dynamic field/eye/keyboard from kb_get_layout()
- render_wifi_setup_result: centered on screen, dynamic button placement
- handle_wifi_setup_touch: matching dynamic hit areas, highlight_rect() feedback
- Rotation lifecycle: enter_wifi_setup_rotation/exit wired into all entry/exit paths
- display_enter_wifi_setup + READY/ERROR touch + SUCCESS auto-return + LIST cancel
- Added kb_result_t typedef to keyboard.h (was only in .c)
- Fixed test_keyboard.c: use computed offsets from kb_layout_t defaults
- All 101 unit tests pass (touch:19, keyboard:46, wifi_setup:36)
