SETTINGS-35: species $/bdft in Settings + taxonomy parent fix (#76)

Add Settings species pricing UI (children of Species grouper by slug,
never hardcoded ids). Map Woo REST parent→parent_id on taxonomy sync;
upsert categories so slab FKs survive re-sync. Tests: parent map, FK-safe
sync, TV-8 0.96×12.50→12.00, Playwright mock e2e. UAT verified on 5060.
