fix(wallet): fetch activeTranscoderCount and delegatorsCount from subgraph

getProtocol() was hardcoding activeTranscoderCount: 0 and
delegatorsCount: 0 instead of querying them from the subgraph.
The Explore Overview cards showed "0" and "—" for these values.

Also added inflationChange, paused fields and fixed participationRate
to multiply by 100 (matching Express backend percentage format).
