Phase 871: protomux-rpc MEMBER_PAGE_REQUEST pull (v0.8.838)

Opt-in member page RPC pull mirrors guild sync request wire: _buildMemberPagePayload,
_handleMemberPageRequestRpc, _tryMemberPageRequestRpc, RPC-first requestGuildMemberPage
with gossip fanout fallback. Non-breaking; default event path unchanged.
