fix(adapters): Select typed the option name when the option did not exist

[AminChirazi]

Re-landed onto main. The original stack (#317/#319/#321/#322/#326) merged into each other's branches rather than up to main, so only #316 actually landed. These five commits are the unchanged remainder, rebased onto current main.\n\nStacked, and the last of them. Re-land of #326.

A JS exception inside call_js_fn does not reach Rust as an Err, so the throw on a missing option was indistinguishable from "this is not a <select>" — the one case the code below it handles — and fell through to typing the option's name into the dropdown.

Typing into a <select> is itself a prefix search, so the step landed on whatever option starts with the same letters and reported success. A plausible wrong answer, chosen quietly.

The two cases are now different answers: not_select keeps the fall-through, a name matching nothing fails naming it. Prefix matching is untouched — value, then exact text, then prefix — so Audit selecting Auditor stays correct.

I had a test case wrong at first and fixed the test, not the code: I asserted Audit must fail. It must not. The comment records why that case is deliberately absent.

Red path plus the green half, because a fix that made every select fail would pass the red test alone.

The one question: still a recording — this removes a path where the trace claimed one option and the app got another.
