• amended app init mechanism, likely fixed various strange issues
• fixed possible NullPointer in episodes lists on startup
• use one time request to schedule feeds refresh, more flexible and hopefully more timely and more frequent
  • Android may kill the refresh process if it takes over 10 minutes
  • in case of errors (including being killed), retry is scheduled for maximum of 3 times at interval of a quarter of the refresh interval
  • retry is only performed on feeds not refreshed previously
• in Settings, renamed the Downloads screen to Network and Downloads, and shuffled some items with the Playback screen
• in Settings->Network and Downloads
  • feeds refresh interval is now set in minutes (not hours)
    • default to 360 minutes, sorry no migration
    • not sure how frequent Android allows reliably (2 minute interval has been tested OK)
    • it should be set longer than the refresh duration which can be a few minutes it you have many feeds and a slow network
  • removed start time setting (on every interval setting, the schedule restarts)
• amended streaming on mobile confirmation mechanism
  • it only appears when stream button on a list is clicked
  • if Once is tapped, it starts streaming the current episode, and all following episodes (on a queue) without further confirmations
• in FeedDetails screen
  • avoided possibly double assembling list
  • likely fixed current playing progress not updating issue
• in episodes lists, a past-due episode (Again or Later) is highlighted
• added experimental feature of scheduling playing episodes
  • in any episodes list, swipe action (also in the Combo) pop up setting for "Play episode at time"
  • the episode will be played if media is ready or streamed
  • multiple schedules are allowed
  • start time is precise as set. note, after scheduling, the app should not be force-stopped, or battery-optimized
  • currently:
    • schedule is only for the next 24 hours
    • there is no further control on it
    • at the end of the episode, it may continue onto other episodes (depending on the feed or the queue)
• restored alternative action buttons menu left out since 8.20.0
• fixed failure downloading previously partially/fully downloaded media
• moved some disk access calls to IO dispatchers to speed up launches
• ensured shared text starts the app in the right screen
• ensures full updates action from Subscriptions menu (though not quite necessary)
• made vms in EpisodeLazyColumn immutable
• OnlineFeed screen not exits when ShowTabsDialog is dismissed
• Kotlin upped to 2.2.20, krdb to 3.2.9
• in build.gradle, replaced setting --no-version-vectors
• some code refactoring and cleaning
