fix: settle a site approval on the port that carries its teardown (closes #275)

Approve and window.close() left the popup on the next line, and the decision
and the disconnect the close caused travelled independent channels with nothing
ordering them. The disconnect handler settled a pending site approval as a
rejection, so whichever landed first decided the outcome. Driven in a tab the
teardown won every time: the user allowed the connection and the dApp was told
they had refused.

The decision now goes out on the approval port the popup already opens, which
is the same port the close disconnects. One channel is ordered -- a message
posted on a port is delivered before that port's own disconnect -- so the
approval is settled before the teardown is even seen, and the disconnect then
finds nothing pending to reject. Nothing waits, nothing is timed, and the popup
closes exactly as immediately as before.

windows.onRemoved no longer decides a site approval whose port is connected
either. In the fallback-window shape that event races the decision on a channel
of its own, which is the same defect one level over; the port disconnect says
the same thing in a defined order, so it is left to say it. A window that
closes before its popup ever connected has nothing else to speak for it and is
still rejected there, so no dApp is left waiting on a window that is gone.

Rejecting reports a rejection, and so does closing without deciding, in both
shapes. AUTISTMASK_APPROVAL_RESPONSE is gone; the port name carries the
approval id, so the popup no longer names one, and the sender check the message
carried moved to the port.

tests/backgroundApproval.test.js drives decide-then-disconnect with nothing
awaited in between, in the toolbar-popup shape that production uses and in the
fallback-window shape, and asserts every close-without-deciding path still
rejects. tests/e2e/run.js drops the deferred-window.close() accommodation it
carried for this bug, so the two site-prompt tests now drive the shipped
decide-then-close in a real Chromium.

 # Completed Steps
 
-- 2026-08-17: The Settings screen is driven in a browser, and every element id
-  the popup looks up is checked statically. Nothing exercised Settings in the
-  e2e suite, and jest runs with no DOM, so the densest run of `$("...")` lookups
-  in the codebase was unverified at runtime. Seven new cases in
-  `tests/e2e/run.js` reach Settings, assert the About well and the wallet list
-  were actually written, assert the four Token Spam Protection checkboxes are
-  real checkboxes defaulted on, and assert the theme and network selectors offer
-  the choices `src/shared/networks.js` and `index.html` define. The selectors
-  are then driven to `dark` and `sepolia` — neither is the first `<option>`, so
-  neither can be read back from the markup with no JavaScript involved — and
-  reasserted after a popup reopen before being restored the same way, and one
-  spam filter is toggled off and back on across a reopen each way. Those round
-  trips run the change handler, `saveState()`, `loadState()` and the
-  `init()`/`show()` assignments rather than just looking at the screen. `show()`
-  no longer guards its `settings-network` lookup with `if (networkSelect)`: a
-  missing element must fail loudly, which is the whole failure mode this unit
-  exists to catch. Each group records a coverage key and a final case demands
-  the exact set, so a shortened or skipped section reddens the run instead of
-  shrinking it. `tests/popupElementIds.test.js` is the general half and runs in
-  `make check` with no browser: every literal id reached through `$()`,
-  `document.getElementById()`, `showError()`/`hideError()` and `showView()` must
-  exist in `src/popup/index.html`, which no id in `index.html` may define twice.
-  Demonstrated on four deliberate breaks — a typo'd id (both halves red), a
-  handler bound to the wrong but existing element (only the functional e2e case
-  red), a typo in a view no browser suite opens (only the static guard red), and
-  the deletion of both persisted-value assignments in `settings.js` (only the
-  selector round-trip case red)

-- 2026-08-14: A background message handler that throws now rejects the page
-  instead of hanging it. `handleRpc(...).then(sendResponse)` had no `.catch()`,
-  and `sendResponse` is the only thing that settles the dApp's
-  `window.ethereum.request()` promise — so any throw inside `handleRpc` left
-  that promise pending forever, with no error and no timeout, indistinguishable
-  from a slow wallet. It now answers `{ code: -32603, message }` (the JSON-RPC
-  internal error EIP-1474 defines and EIP-1193 defers to; no EIP-1193 4xxx code
-  describes "the wallet broke" and none was invented) and logs the method and
-  the throw to the background console rather than swallowing them. The two async
-  IIFEs behind `AUTISTMASK_TX_RESPONSE` and `AUTISTMASK_SIGN_RESPONSE` were the
-  same shape one level down — every statement inside a `try`, but a throw out of
-  a `catch` block escaping unhandled — and each got a last-resort `.catch()`
-  settling the approval through `settleApproval()` and answering the popup. The
-  transaction one tracks which phase it escaped from and reports that, so an
-  escape before `broadcastTransaction()` says the request is gone rather than
-  that it may still have reached the network. Every other handler on the path is
-  synchronous. All four are driven by real failures — a rejecting storage read,
-  and a failure classifier that throws while classifying a genuine verification
-  or broadcast failure — and were demonstrated failing first, the RPC one with
-  `sendResponse` at zero calls
-  ([#280](https://git.eeqj.de/sneak/AutistMask/issues/280)).
