Description

NYM swap partner (nymswap) transactions rendered the generic "Swap Funds" icon in transaction history and details because pluginIdIcons in src/actions/CategoriesActions.ts had no entry for the nymswap plugin id. This adds that mapping so the partner icon renders.

Path note: the icon asset is served at https://content.edge.app/exchangeIcons/nymswap/icon.png (verified 200 image/png), not the flat /nymswap.png path (403), so the entry uses the exchangeIcons/<pluginId>/icon.png convention (the same path src/util/CdnUris.ts builds for exchange icons). This is the same class of bug as the n.exchange task; the flat-path form used in EdgeApp/edge-react-gui#6075 resolves to a 403, which is why that icon is still missing.

Testing: forced pluginIdIcons.nymswap on the transaction rows via a throwaway local harness (reverted before commit) and confirmed the NYM partner icon loads from the content server and renders in the Ethereum Network transaction list on the iOS simulator (edge-funds). tsc --noEmit, jest, and eslint pass. Proof screenshot attached below.

Note

Low Risk
Single CDN URL mapping for display icons; no swap, auth, or transaction logic changes.

Overview
NYM swap (nymswap) transactions now show the partner icon in transaction history and details instead of the generic swap placeholder.

Adds a nymswap entry to pluginIdIcons in CategoriesActions.ts, using the content-server path exchangeIcons/nymswap/icon.png (the flat /nymswap.png URL returns 403). CHANGELOG updated for 4.50.0.
