End-to-end test state fixtures (#7663)

* Add network store for testing An alternative persistent state store has been created for use with e2e tests. Instead of reading state from disk, it tries to load state from a local fixture server running on port `12345` and serving state from the path `/state.json`, and returns a blank state otherwise. * Add e2e test fixture server A fixture server has been added for serving background state, which the background will read upon startup as part of restoring persisted state. The `signature-request` e2e test has been updated to use a fixture to bypass the registration step. The fixture used (`imported-account`) was generated by pausing midway through that test run

+# End-to-end tests
+
+This directory contains the fixture data used to bootstrap the individual e2e tests. Each sub-directory contains
+one thing:
+
+1. A `state.json` file that represents a the saved state for the extension (see _Generating fixture data_ below)
+
+## Generating fixture data
+
+Fixture data can be generated by loading the unpacked extension, inspecting the background context,
+dumping `chrome.storage.local`, and using [`copy`][1] to copy it to the clipboard, and manually pasting the contents into
+a file on disk.
+
+```js
+// Step 1:
+chrome.storage.local.get(null, (x) => console.log(x))
+// Should print something like:
+// > temp1
+// > {data: {…}, meta: {…}}
+
+// Step 2:
+// Store the value as a global via the 'Store as global variable' option in context menu (shown below)
+
+// Step 3:
+copy(temp1)
+```
+
+Store the value as a global variable:
