Migrate transcripts events to Event Horizon

[MiSikora]

Description

This migrates transcripts events to Event Horizon.

Relates to PCDROID-419

Testing Instructions

I would mostly focus on the code review and smoke test some of these events as the migration process is rather a mechanical one.

• transcript_shown
• transcript_dismissed
• transcript_error
• transcript_search_shown
• transcript_search_next_result
• transcript_search_previous_result
• transcript_generated_paywall_shown
• transcript_generated_paywall_dismissed
• transcript_generated_paywall_subscribe_tapped

Pull request overview

Migrates transcript-related analytics from the legacy AnalyticsTracker/AnalyticsEvent system to Event Horizon, ensuring transcript UI interactions emit strongly-typed Event Horizon events across the transcripts feature and player.

Changes:

• Replaced transcript event tracking in TranscriptViewModel (error + search events) with Event Horizon events.
• Updated transcript UI entry points (episode transcript dialog + player transcript page) to emit Event Horizon events for transcript shown/dismissed and generated-transcript paywall interactions.
• Updated transcript type mapping to use Event Horizon’s TranscriptType enum and adjusted unit tests to construct the ViewModel without AnalyticsTracker.
