fix: one transaction approval at a time, and honest copy for a nonce collision (closes #271 )

Populating the transaction in the background before the approval window opens is what makes the displayed object the verified object. It also fixes the nonce before the user has answered anything, so two eth_sendTransaction calls populated concurrently took the same nonce from a node that had seen neither of them broadcast, and the second could never be sent: its approved nonce is spent, and the only way to give it a fresh one is to populate it again after the user has read the old one off the screen. A second transaction approval is now refused while one is unanswered, with EIP-1193 code -32002. The refusal happens before anything is populated — no second nonce is allocated, no window opens — and the slot is released when the requesting page has its answer. Signature approvals are not gated; a signature consumes no nonce. A collision that does happen is now reported for what it is. A broadcast the node refused for the nonce, and an approval carrying a nonce this worker has already broadcast (caught before the node is asked at all), both report that the transaction did not reach the network and to send it again, instead of the standing broadcast wording that warns it may have sent. "already known" keeps that ambiguous wording deliberately: a node that says it has the transaction has it. Nothing about verification is weakened. The approval still carries the transaction the screen displayed, and the artifact is still compared against that object field for field.

 # Completed Steps

- 2026-08-14: `make check` does static analysis. `script/lint` ran
-  `prettier --check .`, byte-identical to `script/fmt-check`, so a wallet with
-  two shipped used-but-not-imported crashes behind it was green. ESLint is now
-  pinned in `package.json` with `@eslint/js` recommended as the base, flat
-  config in `eslint.config.js`, `no-undef` and `no-unused-vars` error-level, and
-  globals declared per tree — browser for the popup and content scripts, service
-  worker for `src/background/` and `src/shared/`, jest for `tests/`, node for
-  `build.js`. It found 41 unused bindings and 53 undefined identifiers; all are
-  fixed, and dropping a call to an unimported `foo()` into any `src/` file fails
-  `make lint`. Linting is also containerized now: `script/lint` builds the
-  Dockerfile's new `lint` stage, so the ESLint that decides whether this repo is
-  green is the pinned one and not the host's
