Add IPTV VOD browsing as a Library tab

[test01203]

Summary

IPTV subscriptions carry a VOD catalogue — often thousands of movies and series — that ARVIO could reach only indirectly: an IPTV copy shows up as a source on a Details page you already found some other way. There was no way to browse what the provider actually has.

This adds that catalogue to Library, as a tab, next to the home servers. The TV screen is untouched and stays live-only.

Reworked from the first version of this PR, which added a VOD destination to the top bar. Per @Himanth-reddy and @ProdigyV21 that is not where it belongs: the data layer, caching and TMDB matching are kept, the browsing UI moved into Library, and the top-bar entry is gone entirely.

What the tab does

• Sources rail — "All", "Recently added", then the provider's own categories. Empty categories are hidden. On mobile this is the existing "Choose library" picker; on TV it is the same side rail the home servers use.
• Filters → Type picks Movies or Series. The provider keeps those as two separate catalogues, so this chooses which one to read rather than filtering one list; there is no combined option, and sorting is left out because the order is the provider's own.
• Search uses the Library's existing search box.
• Opening a title: one the provider tagged with a TMDB id opens ARVIO's normal Details page, where the IPTV copy appears as a source next to the addons. An untagged one is matched on TMDB by cleaned name and year. A movie that still cannot be matched plays straight from the provider; anything else reports which title could not be opened instead of failing silently.
• The tab only exists when a playlist can actually serve VOD, and it disappears again if that playlist is removed.
• The catalogue is read when the tab is first opened, not when Library is. Opening Library costs one cheap config read.

Data layer

IptvRepository.getVodBrowseCatalog(series) reads the provider's movie or series list through the same memory and disk caches that already back IPTV VOD source matching, so the second visit is instant. Three browse-only fields were added to the Xtream models (stream_icon/cover, rating, added/last_modified) and the disk cache filenames bumped to _v2 so an older cache without them is re-read once.

Titles carry provider noise — EN - , |HE|, [4K], 1080p, a trailing year — so cleanIptvTitle strips it for both the TMDB lookup and the card label.

A title with no TMDB match plays under a negative synthetic id, and the player skips history and scrobbling for ids <= 0 so an unmatched stream cannot write junk into Continue Watching.

Test plan

• ./gradlew :app:compilePlayDebugKotlin
• ./gradlew :app:testPlayDebugUnitTest
• CleanIptvTitleTest covers the provider prefixes, quality tags and trailing years.

I think this would fit ARVIO better if we implement the VOD browsing within the existing Library instead of adding a separate VOD section next to TV.

I’d keep the TV section unchanged and use it purely for live IPTV. The VOD catalogue from IPTV can be exposed as another source/filter inside Library, since Movies, Series etc. already conceptually belong there.

So I’d suggest keeping the underlying IPTV VOD catalogue/caching/matching work from this PR, but moving the browsing UI into Library rather than introducing a separate VOD destination.

Like Himanth said, adding something in topbar is not in Arvio's vission. Great Pr tho, we can use this.
Instead add a tab in Library page like it does for homeservers would fit this better. Make sure to fully test it on mobile and tv. Dm me about this and I can give you premium so you can also test for webapp.

Thanks!

Do you have screenshots of it and tested it? @test01203
