Add SimpleSwap swap provider

CHANGELOG

Does this branch warrant an entry to the CHANGELOG?

• Yes
• No

Dependencies

EdgeApp/edge-exchange-plugins#481 — the SimpleSwap plugin itself. This PR only registers it, so it is inert until that lands and publishes.

Requirements

If you have made any visual changes to the GUI. Make sure you have:

• Tested on iOS device
• Tested on Android device
• Tested on small-screen device (iPod Touch)
• Tested on large-screen device (tablet)

Description

Asana: https://app.asana.com/0/1215088146871429/1217205278669378

Registers SimpleSwap, the swap provider added in
EdgeApp/edge-exchange-plugins#481,
so the plugin the partner wrote actually loads in the app.

• src/envConfig.ts — SIMPLESWAP_INIT with an apiKey, matching the other
  centralized providers. An empty key makes the plugin factory throw, so builds
  without the key skip SimpleSwap entirely.
• src/util/corePlugins.ts — the swapPlugins entry.
• src/components/modals/SwapVerifyTermsModal.tsx — the terms, privacy and
  AML/KYC links shown before the first SimpleSwap quote.
• src/actions/CategoriesActions.ts and src/constants/MerchantContacts.ts —
  the provider icon and merchant contact.

The icon path exchangeIcons/simpleswap/icon.png is not on the content server
yet; the asset upload is an ops step outside this repo.

Testing

Driven on the iOS simulator against the real SimpleSwap API, with every other
swap provider disabled locally so the engine had to route through SimpleSwap:
a live XLM to XMR swap from My Stellar executed to the success scene, and the
Stellar send carried SimpleSwap's numeric deposit memo. Screenshots below.

Note

Low Risk
Registration-only GUI changes with no auth or payment logic; provider stays inactive without an API key and depends on the separate exchange-plugins release.

Overview
Adds SimpleSwap as a centralized swap provider in the app shell, aligned with other partners like SideShift and Swapuz. The live swap logic ships in edge-exchange-plugins; this change only wires the provider into Edge.

Configuration: SIMPLESWAP_INIT in env config accepts an optional apiKey (same pattern as other centralized providers). An empty key means the plugin factory does not load SimpleSwap.

User-facing: First-quote terms, privacy, and AML/KYC links in SwapVerifyTermsModal, plus exchange icon mapping and a MerchantContacts entry for history/details branding.

CHANGELOG notes SimpleSwap as a new swap provider.

Closing as a duplicate: SimpleSwap already submitted the same GUI wiring in #6136, which additionally supplies the logo assets for the content server. I opened this before spotting theirs. The verification stands and the test-evidence screenshots are being moved to #6136.
