Second slice of the z_sendmany split. The ~60-line loop that parses and
validates the "outputs" array — rejecting unknown keys, bad addresses, memos
on taddrs, oversize memos and negative amounts, and sorting recipients into
taddr/zaddr lists while accumulating nTotalOut — is lifted verbatim into
ParseSendManyRecipients(outputs, branchId, taddrRecipients, zaddrRecipients,
nTotalOut).
Verbatim extract-method (the loop text was moved unchanged, not retyped); the
helper reads only outputs + branchId and writes the three by-reference outputs
the loop already produced, which the clean compile proves self-contained (a
reference to any other z_sendmany local would fail to link). Built clean;
verifychain=true.
Together with the SelectAnyZaddrSource slice, z_sendmany is now ~135 lines
shorter, with source-address resolution and recipient parsing separated out.
Remaining: note selection, Sietch padding, and tx assembly (later slices,
best validated against a synced node since z_sendmany's linkability guard
blocks the send path on a peerless node).
