Replace Chrome-remote-debugging login capture with a cookie-paste import flow

Live testing showed the CDP approach still fails hCaptcha even with a
real human clicking through chrome://inspect: the headless Chromium's
own fingerprint (HeadlessChrome user-agent, navigator.webdriver=true)
is what gets flagged, independent of who's driving it. Trying to
disguise that browser to get past bot detection would be captcha
evasion, not a session-handling technique, so that path is dropped
entirely rather than patched further.

New flow: log into MassPrice with an ordinary, non-automated browser
(hCaptcha passes normally), export the session's cookies with a
extension, and paste them into the Session page. import_cookies()
converts the export into Playwright's storage_state shape and verifies
it actually authenticates against the live site before saving it,
so a bad paste never clobbers a working session. This also removes the
now-unnecessary socat proxy / debug port exposure — Chromium's own
CDP port was only ever needed for the dropped approach.
