feat: chain status command + wallet info + core/api SSE tracking

chain status: live chain data from daemon RPC
  height, difficulty, aliases, sync state, HF5 countdown

wallet info: full wallet dump
  standard/integrated/auditable addresses, spend/view keys, seed

core/api now has WithSSEPath() for configurable SSE — ready for
go-blockchain integration when wiring as core/api service.
