Add a "From your Plex Watchlist" Row to Overseerr Discovery Page for Plex-authenticated users

Description

For users who use authenticate with their Plex credentials, it would be great to show their Plex Watchlist as a row in Discovery with the ability to request items not currently available on the server.

Here is an example query builder for the API (from Sonarr):

var requestBuilder = new HttpRequestBuilder("https://metadata.provider.plex.tv/library/sections/watchlist/all")
                    .Accept(HttpAccept.Json)
                    .AddQueryParam("clientID", clientIdentifier)
                    .AddQueryParam("context[device][product]", BuildInfo.AppName)
                    .AddQueryParam("context[device][platform]", "Windows")
                    .AddQueryParam("context[device][platformVersion]", "7")
                    .AddQueryParam("context[device][version]", BuildInfo.Version.ToString())
                    .AddQueryParam("includeFields", "title,type,year,ratingKey")
                    .AddQueryParam("includeElements", "Guid")
                    .AddQueryParam("sort", "watchlistedAt:desc")

if (!string.IsNullOrWhiteSpace(authToken))
{
       requestBuilder.AddQueryParam("X-Plex-Token", authToken);
}

Desired Behavior

On the Discovery page, show a row called “From Your Plex Watchlist” that shows media items for everything you have added to your Plex Watchlist, with the same status and actions as Media Items in other rows (ie, Trending).

Why stop there, I think it would be a dream to make it a permission & user settings option to auto-request anything that shows up on any plex user’s watchlist, then users would be able to effectively request things without leaving the plex app… set it and forget it

[tdeverx]

Plex just added an option to generate an RSS feed for your watchlist, this would essentially allow users to add this “URL” to their profile. This should remove the need to implement a way to scan all users Plex profiles and give users a choice if they want this or not. I also believe scrubbing an RSS feed should be 100x easier to implement.
