## Description
This PR adds the ability to customize the home page in-app
### Features
- Add, remove, & reorder rows
- Persist the configuration locally
- Save the configuration to the server, allowing to pull down on other
devices
- Adjust view options for rows such as card height, image type,
preferring series images, or aspect ratio (similar to libraries)
- Pull down the web client's home rows (no plugins are supported yet!)
- Preview of the home page which is usable & updated as changes are made
### Row options
These are row types that can be added in-app via the UI:
- Continue watching
- Next up
- Combined continue waiting & next up
- Recently added in a library
- Recently released in a library
- Genres in a library
- Suggestions for a library (movie & TV show libraries only)
- Favorite movies, tv shows, episodes, etc
Additionally, there are more row types that don't have a UI to add them
(yet):
- Simple query to get items from a parent ID such as a collection or
playlist
- Complex query to get arbitrary items via the `/Items` API endpoint
### Dev notes
Settings are loaded in order:
1. Locally saved
2. Remote saved
3. Fallback to default similar to Wholphin's original home rows
The remote saved settings are stored via the display preferences API.
I know some server admins would prefer to push a default setup to their
clients. This PR does not have that ability, but it does define a
straightforward API for defining the settings. Something like the
potential server plugin work started in #625 could be slimmed down to
expose a URL to be added in the load order.
I'm also investigating integration with popular home page plugins to
allow for further customization, but will take more time.
