Fix sapling pool persistence and add subsidy/fees to getblock RPC

Browse Source 
Lower SPROUT_VALUE_VERSION and SAPLING_VALUE_VERSION constants in
chain.h from upstream Zcash values (1001400/1010100) to 1000000.
When DragonX was rebranded from HUSH3, CLIENT_VERSION was reset from
3.10.5 to 1.0.0, falling below these thresholds. This caused
nSaplingValue to silently skip serialization, so the sapling pool
total reset to 0 on every node restart. Explorer nodes should reindex
once after upgrading.

Add subsidy and fees fields to the getblock RPC response so explorers
can display the correct 3 DRGX block reward separately from fees,
instead of showing the combined coinbase output as the reward.
