Implements accupdatefamily endpoint (verified via FW_DEBUG=1):
- Parameter 'scope' targets any circle (primary or secondary)
- Without scope: renames the primary circle (API default)
- Server always capitalises the first letter of the new name
- Verifies circle existence via famlistfamily in same session
- Response a00.r.r = full circle object with updated name
Also corrects SPEC.md: accupdatefamily with scope= works for any
circle, not just the primary (previous note was incomplete).
