fix(sea): F3 round-3 — eslint no-unused-vars on 4 underscore-prefix args

DA F3 round-1 M3 finding: airbnb-typescript's `no-unused-vars` rule
does not honor the `_`-prefix convention, so the 4 args in this
test file that are interface-mandated but unused (the IDBSQLLogger
`log(_level, _message)` noop method and the sinon spy
`(_sql, _options) => stmt`) were reported as errors.

Verified the rule config: `.eslintrc` uses
`airbnb-typescript/base` which inherits airbnb-base's
`no-unused-vars` with no `argsIgnorePattern` override.

Two-line fix: `// eslint-disable-next-line` directly above each
site. Both args remain in the signature because they're shape-
mandated by the consumer (IDBSQLLogger interface, sinon spy
function type matching SeaNativeConnection.executeStatement).

Verified `yarn lint` no longer emits errors for
`tests/unit/sea/execution-query-tags.test.ts`. Pre-existing lint
errors on `operation-lifecycle-e2e.test.ts` and
`SeaSessionBackend.ts` are upstream on `sea-auth-u2m` and not
introduced or addressed by this commit.
