Walkthrough

Adds an optional sourceType parameter to event tracking. EventAPIService.trackEvent and EventService.trackEvent signatures now accept sourceType?: string; several call sites (NotificationService, SessionService) were updated to pass 'CLIX'. Package version incremented to 1.4.1.

Cohort / File(s)	Summary
Event API & Service src/services/EventAPIService.ts, src/services/EventService.ts	Added optional sourceType?: string to trackEvent signatures and propagated the parameter from EventService to EventAPIService (emitted payload includes source_type when provided).
Event Tracking Call Sites src/services/NotificationService.ts, src/services/SessionService.ts	Updated trackEvent invocations to include an extra sourceType argument ('CLIX'), adjusting call arity where these events are emitted.
