## Description
When testing the new deep link feature from this PR
[#1688](https://github.com/damontecres/Wholphin/pull/1688)
I noticed that the back button would close the app. As in, all routes
are cleared and only the playback is in the nav stack.
I figured a more desirable behavior would be to create a nav stack,
always starting with the home screen, then also inserting the media
item's details page, if available.
To achieve this, I made the return Target.destinations a list of
destinations, and updated the other two uses in IntentService.
Open to implementation tweaks, or scrap it if this isn't how it should
work, haha.
### Testing
Tested deep links, which produced the following nav stacks:
- Movie view
- Home → Movie details
- Movie playback (with and without position)
- Home → Movie details → Playback
- Series view
- Home → Series details
- Season view
- Home → Season details
- Episode view
- Home → Episode details
- Episode playback (with and without position)
- Home → Episode details → Playback
- Trailer/extras playback (no details page available)
- Home → Playback
- TV channel view
- Home → Playback
- TV channel playback
- Home → Playback
## AI or LLM usage
AI was used to generate the initial code, debug and test, then manual
refactoring and cleanup was done.
