Fixes PCIOS-181

This PR implements the top podcast story

Note: the share image isn't yet implemented because I need to get the circular asset in a transparent image to apply

To test

• Start the app
• Login with an user that has some stats for 2025
• Go to Profile -> Settings -> Beta features
• Enable the FF End of Year 2025
• Go to Developer Menu and tap on "End Of Year -> Reset modal/profile badge" and select 2025
• Restart the app
• Check that if you see the prompt for the End of the Year on the Podcasts screen
• Tap on View My Playback 2025
• It should show the 2024 design but with the stats for 2025 ( some screens for 2024 had the year hardcoded on string/images so ignore those)
• Go to Profile
• Check that you see a banner for the playback 2025
• Tap on it
• Check if Playback screen shows correctly
• Check if the loading and Intro screen show correctly
• Check if Top Podcast story shows correctly and the and background animation is correct.

Checklist

• I have considered if this change warrants user-facing release notes and have added them to CHANGELOG.md if necessary.
• I have considered adding unit tests for my changes.
• I have updated (or requested that someone edit) the spreadsheet to reflect any new or changed analytics.
