Trial onboarding: preserve Nginx / Apache detection from the homepage
When the homepage compatibility checker detected Nginx or Apache and you clicked the email setup link, the dashboard onboarding incorrectly showed "Detected: Cloudflare". It now carries the original detection through and lands on the Vector flow as intended.
If you ran the homepage compatibility checker on a plain Nginx or Apache origin and asked for an email setup link, the trial onboarding page in the dashboard was mis-displaying the detected platform — it showed Detected: Cloudflare and recommended the Cloudflare Worker integration, even though the homepage had correctly identified the server as Nginx or Apache. Continuing through still worked because the Vector tile was available below, but it was confusing and added extra clicks.
Fixed: the trial session now maps nginx and apache detections through to the Vector source type, so you land directly on the Apache / Nginx (Vector) option with the right server radio and log path pre-selected.
