[HLS] Implement analytics

[sztomek]

Description

This PR integrates the latest version of EventHorizon that contains the necessary analytics events and proprerties.
New events:

• playback_source_resolved - fires on every episode open
• playback_hls_toggled - fires when show/hide video shelf action is tapped while playing a hls stream
  Enriched properties of existing events:
• playback_play - hls_available, audio_only_mode are new ones
• playback_episode_completed - same as above
• playback_failed - podcast_uuid (if the episode is known), source (where playback was triggered, content_type, playback_protocol (hls if the failing stream was HLS, else progressive), hls_error_detail = the Media3 error code (e.g. ERROR_CODE_IO_NETWORK_CONNECTION_FAILED) only for HLS failures; omitted otherise

Fixes PCDROId-640 https://linear.app/a8c/issue/PCDROID-640/analytics

1. Build and install app
2. Make sure hls_streaming is enabled
3. Select a podcast that has hls streams like We Have A Meeting

Resolved the merge conflicts. Two files had conflicts:

• gradle/libs.versions.toml: kept the newer EventHorizon version from main (pocket-casts-2026-07-02_08-30-44)
• PlaybackManager.kt: preserved all analytics additions from this branch (HLS availability tracking, PlaybackSourceResolvedEvent, PlaybackHlsToggledEvent, and the audioOnlyModeOrNull/playbackContentTypeFor helpers) while integrating the restructured applyStreamOverride logic from main
