update test_last_full_moon.py to produce the full moon image

Now runs the complete production pipeline without east-frame verification:
find last full moon → fetch NASA Dial-a-Moon render → render_phase_closeup
→ test_last_full_moon_out.jpg with caption (phase, % lit, local time,
NASA attribution).

Also retains the sun_events_in_range() call as a regression check for
the sunrise_sunset() bare-topos fix.

-Exercises:
-  - full_moons_in_range()        — phase detection
-  - sun_events_in_range()        — sunrise/sunset almanac (requires bare topos, not earth+topos)
-  - illumination() / altaz() / parallactic_angle()
+Runs the same NASA Dial-a-Moon fetch + render_phase_closeup pipeline that
+moon-phase-monthly.sh uses, but bypasses the east-frame witness step so it
+works any time without needing captured frames.
+
+Also exercises sun_events_in_range() (the sunrise/sunset almanac call that
+requires a bare topos, not an earth+topos observer) as a regression check
+for that fix.
+
+Output: test_last_full_moon_out.jpg in the sky-cam directory.
