Render the portfolio trend sparkline in every row style, each with a layout that features it:
- Table: a dedicated header-labelled TREND column (48dp rows), aligned across rows.
- Cards: a left-aligned info stack (icon + label / value+delta chip / DRGX) with a full-height sparkline filling the rest of the width (content-driven, so short groups give the chart more room).
- Spotlight: a big-value-over-a-full-width-chart-band hero tile (92dp).
Default sparkline interval is now MONTH (a real curve from the daily series, not the young minute buffer). Removed the per-row container accent line (redundant with the icon/sparkline colour) and the per-group shielded/transparent bar (private-by-default makes it near-always 100%, and dropped its now-dead SumPortfolioSplit helper). DPI-scale the sparkline stroke. Adds the "Trend" column string across 9 languages.
Relocated the Market controls out of a removed settings modal + gear: the chart line/candle picker now sits top-right of the chart (left of the trade button, candle-capable ranges only), and the Table/Cards/Spotlight picker sits left of Manage. Dropped the market fetch-prices toggle (still in the general Settings page).

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.
