feat(suite): report settings/networks/explorer analytics event

[vojtatranta]

Report the explorer event on Desktop only when the saved explorer configuration actually differs from the stored one, so a backend-only Confirm or a purely cosmetic edit emits nothing.

Extract the explorer normalization out of the reducer into pure helpers shared via wallet-core, so the same comparison can be reused on Mobile.

🤖 LLM Test Recommendations

Summary: The change set centers on the coin backend/explorer settings form, reducer, and related analytics events. The highest-risk paths are the Settings > Coins custom backend UI and the analytics events emitted when backends change. Running the two high-priority tests provides direct coverage of these flows; the medium-priority tests extend confidence to alternative backend types (Electrum, Blockbook) and the broader coins settings page. No low-priority tests are recommended because the changed files are broad dependencies and the remaining tests do not plausibly exercise the backend/explorer path.

Recommended tests (5)

🔴 High priority (2)

• suite/e2e/tests/analytics/events.test.ts — This test explicitly changes custom coin backends in settings and asserts that the SuiteReady analytics event reflects the updated customBackends value. The changed analytics event files (settingsCoinsBackendEvent) and explorer reducer are directly on this code path.
• suite/e2e/tests/settings/coins-custom-backend.test.ts — Directly exercises the Settings > Coins custom backend flow: toggling networks, configuring correct and incorrect Blockbook backend URLs, checking the custom-backend indicator, and verifying discovery. This is the primary UI path affected by changes to useExplorerForm and the explorer reducer/utils.

🟡 Medium priority (3)

• suite/e2e/tests/settings/coins.test.ts — Covers the Coins settings page including enabling assets and configuring a custom Blockbook backend for ETH with the backend indicator. It shares the same settings UI and backend configuration state as the changed files.
• suite/e2e/tests/settings/electrum.test.ts — Configures a custom Electrum backend for regtest and verifies discovery and balances. This exercises an alternative backend type managed by the same explorer/backend state and settings form infrastructure.
• suite/e2e/tests/wallet/blockbook-discovery.test.ts — Sets custom Blockbook backends for BTC and LTC and asserts that discovery completes and the portfolio graph loads. It validates the backend configuration state end-to-end after settings changes.

⚠️ Changes with no test coverage (1)
