Foundation for the Market tab's configurable portfolio (custom labels tied to
groups of addresses):
- Settings gains a PortfolioEntry {label, addresses[]} list, persisted in
settings.json as a JSON array-of-objects (same mechanism as lite_servers_),
with get/setPortfolioEntries().
- data/portfolio.h (header-only, ImGui-free): SumPortfolioBalance() sums a
group's DRGX balance against the live per-address list (unknown addresses
contribute 0), plus PortfolioEntryContains/Add/Remove group helpers.
- Unit-tested (testPortfolioHelpers): empty/known/unknown-address sums, and the
add/remove/contains membership semantics.
UI (editor dialog, Market card rework, Overview right-click) comes next.
Full-node + lite build clean; ctest green.
