Instrument Pendo Track Events

[novus-by-dhruv]

Summary

Adds Pendo Track Event instrumentation across 8 Angular components to capture 24 key user interactions including authentication flows, course/skill search, content creation, voting, and profile management. All events use client-side pendo.track() calls placed in success callbacks with relevant metadata properties for analytics segmentation.

Changes

• Added user_registered, user_logged_in, and password_reset_requested track events to login.component.ts
• Added email_verification_resent track event to verify-email.component.ts
• Added course_search_executed and course_name_search_executed track events to homepage.component.ts
• Added skill_search_executed track event to skill-search.component.ts
• Added student_search_executed track event to search-student-by-name.component.ts
• Added course_added track event to add-acourse.component.ts
• Added course_pinned, course_unpinned, course_review_submitted, review_voted, faq_question_asked, faq_answer_submitted, course_content_uploaded, content_voted, and faq_answer_deleted track events to course-details.component.ts
• Added review_deleted, content_deleted, skill_added_to_profile, skill_removed_from_profile, and notifications_cleared track events to myprofile.component.ts
• Added new_skill_created track event to add-skill.component.ts
• Added declare var pendo: any; to all 8 modified component files for TypeScript compatibility

Notes

• All track events are client-side using the global pendo.track() API — requires the Pendo agent to be installed and initialized in the application
• Vote events (review_voted, content_voted) capture three action types: 'new', 'reverse', and 'switch' to distinguish between fresh votes, vote removals, and vote direction changes
• The notifications_cleared event captures the count before clearing so the notification volume is preserved in analytics
• Search events fire on each autocomplete result set returned, not on debounced input — this matches the existing code's throttle behavior
