Login slots: 1,000 credits, at most 3 member slots live; viewer gets an open-in-tab link

Marty (2026-09-19): cap the login-ad slots. About 124 members sign in a day and every live
slot shares those views, so a fourth slot only thins the other three. Member slots only;
house login ads now step aside whenever a member slot is running (JSON: filtered out of the
pool; MySQL: ORDER BY house ASC). The 14 slots already running keep their term; new buys are
refused until one ends. Format label and chatbot updated.

mindfulmojo (email, 2026-09-19): the viewer frames the advertiser's page and both controls
meant "back"; some sites refuse to load inside a frame and signing up is easier in a full tab.
The viewer bar now carries "Open site in a new tab", set from the ad's target URL.
