fix: fixed ordering of episodes and shared episodes

[SamTV12345]

Description

• This mr fixes two things. Firstly the podcast episode logs weren't ordered correctly by timestamp .This caused webview not respecting progress on the app.
• Secondly I thought about the app syncing. Generally you don't want to sync every podcast to every device but syncing the progress between devices should be a most so you can listen on your iPad to the same podcasts like on your phone
