- Buying now ensures the wallet is LINKED to the account before the purchase
(one signature if not linked). Without it, a wallet only connected for the
faucet bought successfully but credits resolved against member id 0 and never
showed until a manual link. Matches the "buying links your wallet" promise.
- Dashboard computed achievement milestones from buyerCount BEFORE reading it
from chain (always 0), so Surge/Circuit/Nexus never unlocked even when
qualification advanced. Moved the milestone block after the chain read.
