fix: use moodType=STAR for wallmood, parse moodMap from response (v0.4.4)

FW_DEBUG=1 verification revealed:
- moodType "LIKE" was silently mapped to "STAR" server-side; use "STAR" directly
- Response a00.r.r contains full wall object with moodMap showing actual like state
- liked status now derived from moodMap rather than echoing the input bool
- SPEC.md updated with fully verified wallmood endpoint details
