feat(portfolio): Market card entries + "Manage" editor dialog

Build the configurable-portfolio UI on the persisted model:
- The portfolio card keeps the "all funds" summary and now renders each custom
  entry below it as a compact row (label · summed DRGX · USD), live-computed via
  SumPortfolioBalance over the wallet's per-address balances; the card grows to
  fit the entries.
- A right-aligned "Manage…" button on the card header opens a modal editor
  (material overlay dialog): list entries with Edit/Delete, "Add entry", and an
  edit form = label field + quick "All shielded / All transparent / Clear"
  selectors + a checklist of wallet addresses (with balances). Persists to
  Settings on each mutation.
- i18n English defaults for the new portfolio_* strings.
- Test namespace fix (AddressInfo is dragonx::, not dragonx::data::).

Full-node + lite build clean; ctest green; source hygiene clean. Remaining:
the Overview-tab right-click "add/remove address to a label" integration.
