Bambuddy sync: match the real spools API
Checked against Greg's Bambuddy: the key goes in X-API-Key, colors are color_name (often null on RFID spools) and rgba, grams left is label_weight minus weight_used, and archived spools carry archived_at. Unnamed spools get the nearest plain color name. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_012aSbo2D1qP8cMFQCykf7kx
