Completes the approved trial flow end to end. The License panel's plan
comparison gains a 'Start 14-day free Pro trial' action (shown only when
unlicensed, trial-eligible, and never-trialed) that rides the existing
purchase-start handoff with trial=1; the handler already forwards
non-reserved params. Pulse Account portal reads the trial arrival flag,
relabels the pro monthly checkout button, shows the card-required note,
and sends trial:true to the checkout session endpoint (server support
deployed in pulse-pro 4c3a28c). Organic portal and public pricing
arrivals see no trial anywhere, per the no-upsell doctrine; retired
local trial-acquisition routes remain 404. Portal dist rebuilt.
