fix: suppress USD display on testnet networks (#142)
## Summary

Fixes USD prices still showing on the main view when connected to a testnet (e.g. Sepolia). The root cause was stale mainnet prices lingering in the in-memory price cache after switching networks.

### Root Cause

PR #137 correctly made `refreshPrices()` skip fetching on testnets, but the cached prices from a prior mainnet session remained in the `prices` object. All display functions (`getPrice()`, `getAddressValueUsd()`, etc.) used whatever was cached without checking which network was active.

### Changes

- **`src/shared/prices.js`**
  - `refreshPrices()` now clears the price cache when on a testnet instead of silently returning
  - New `clearPrices()` function empties the cache and resets the fetch timestamp
  - `getPrice()` returns null on testnets (defense-in-depth)
  - `getAddressValueUsd()`, `getWalletValueUsd()`, `getTotalValueUsd()` return null on testnets

- **`src/popup/views/settings.js`**
  - Network switcher immediately clears prices when switching to a testnet, so the UI updates without waiting for the next refresh cycle

closes #139
