- Rename the portfolio heading "MY DRGX" -> "PORTFOLIO".
- Group cards are now clickable: clicking one opens the editor directly on that
group (edit mode), with a hover highlight + hand cursor.
- PortfolioEntry gains an `icon` (project_icons wallet-icon name) and a `color`
(packed IM_COL32 accent); both are persisted in settings.json.
- Editor edit-mode gains an icon picker (the same wallet icon set as the overview
tab's address-label dialog, via material::project_icons) with a "None" option,
and a color picker (preset accent palette + a default/no-color swatch).
- Group cards render the chosen icon to the left of the name and, when a color
is set, a left accent bar + the icon tinted in that color.
Full-node + Lite build clean; ctest 1/1; hygiene clean. Rendering change — needs
a screenshot check of the Market portfolio + the editor.
