Solve captchas through the 2captcha API, not its extension

Browse Source 
The two Tradeify automations clicked the 2captcha *extension's* solve button
and waited for it to go green. That needed a second extension installed and
signed in, put a real mouse click on a button whose markup is 2captcha's to
change, and gave a run no way to tell "still solving" from "not installed".

Replaced with one `solveCaptcha` step. No mouse: the extension reads the
widget's sitekey out of the page, the dashboard buys a token from 2captcha,
and the extension puts it in the response field and fires the page's own
callback.

captcha-hook.js is the part that earns its keep. A widget rendered
programmatically puts nothing in the DOM — no sitekey, and no callback. Most
pages only enable submit from that callback, so filling the hidden field alone
leaves the page looking unsolved. The hook wraps turnstile/grecaptcha/hcaptcha
`render` at document_start to hold on to what the page passed.

Solves go through 2captcha's residential proxy. Its API rejects host names in
proxyAddress, so na.proxy.2captcha.com is resolved to an IP first (cached);
the gateway was confirmed to work addressed that way.

Covers reCAPTCHA v2 (incl. invisible and Enterprise), hCaptcha and Turnstile.
NOT reCAPTCHA v3: a v3 page carries an anchor iframe with k=, so it is
detected as v2 and would be solved with the wrong task type. Everything else
unsupported fails loudly instead.

The API key and proxy credentials are hardcoded in the captcha route on
request. Unlike the sqlite database, that file is in the repo, so they travel
with it. TWOCAPTCHA_API_KEY / TWOCAPTCHA_PROXY and the settings rows still
override; neither has a field on the Settings page.

Runner VERSION and RUNNER_EXPECTED_VERSION both to 0.17.0 — they are a pair,
and a mismatch shows as a red "restart your runner" banner that blames the
wrong process.
