Add ECX GUI wiring

[samholmes]

Summary

• Register the new bitcoinecash currency plugin behind a separate BITCOINECASH_INIT gate so ECX stays distinct from existing XEC ecash.
• Add ECX GUI metadata for SegWit/import/max-spend behavior.
• Add ECX to wallet menu sign-message and xpub-view capability lists.
• Temporarily pin edge-currency-plugins to the ECX PR branch at 4047454915becfe680098f550ca12ab6545f12d8 until the plugin PR is merged and released.

Correlated plugin PR: EdgeApp/edge-currency-plugins#456

Testing

• npx eslint src/util/corePlugins.ts src/envConfig.ts src/constants/WalletAndCurrencyConstants.ts src/__tests__/constants/WalletAndCurrencyConstants.test.ts src/components/modals/WalletListMenuModal.tsx
• git diff --check
• npx tsc --noEmit
• npm test -- src/__tests__/constants/WalletAndCurrencyConstants.test.ts --runInBand
• npm test -- --runInBand --findRelatedTests src/components/modals/WalletListMenuModal.tsx --passWithNoTests
• precommit hook: tsc + full npm test (98 suites / 705 tests passed)

Notes

• ECX remains disabled by default because missing BITCOINECASH_INIT cleans to false; this avoids enabling the pre-launch/drynet wallet unintentionally.
• ECX currently reuses the existing user-facing My eCash wallet-name string; no ECX-specific localization key exists yet.

Shared ECX and XEC wallet name

Low Severity

ecashcom reuses lstrings.string_first_ecash_wallet_name (My eCash), the same default as XEC ecash. getUniqueWalletName only uniquifies within a pluginId, so both wallets can appear with identical names, which undercuts keeping ECX distinct from XEC.
