Goal to create a package fastn-log for full-spectrum analytics
A custom fastn-based event logging system is needed to collect events from all layers: Frontend, Backend, APIs and Other internal systems

Steps:

• in fastn_migrations.rs add migration for fastn_event table
• create ft_sdk::create_event method (update lets-auth etc to use this)
• lets-event-log: fastn package
  • dashboard: so you can see / filter events
  • /-/event/create/ to be called from JS/django. all data will come from query params, uid will be take from sid.
• ftd.js: ftd.create_event(): will call the backend /-/event/create/.
• ftd.document to contain some on page load event data also (eg do not send this page's page load to GA)
• ds.text-input component should expose component properties to identify the form field, and then auto create events for field-focus, field-plug, field-change.

-- void create-text-post(title, is_public):
ftd.string-field $title:
ftd.boolean-field $is_public:
string action_url: $ftd.app-url(path=/backend/create-text-post/)
js: external.js

ftd.submit_form(action_url, title, is_public, ("external:event-name", "create-text-post"))

CREATE TABLE fastn_event IF NOT EXISTS (
    id, 
    okind, oid, ekind, data, dimensions, metrics,
    uid, sid, tid, ip, user_agent
);
