test(e2e): use aliases for permit2 test (#6656)

* test(e2e): disable video compression

* refactor: improve popupList impl/test

* test(e2e): log JSON-RPC calls

* fix: retry backoff logic

* test(e2e): wait for hardhat/popup assertions

* fix: remove transactions after expired

* test(e2e): re-enable other swap tests

* chore: rm console.log

* fix: expire txs after 6h

* refactor: dry trade info

* test(e2e): use default deadline

* test(e2e): use aliases for permit2 test

* test(e2e): automine/off in beforeEach
