The horizontal channel chip strip looks awkward on tvOS and the focus
interaction is clunky. Drop it from the tvOS branch of InstanceBrowseView;
other platforms keep it.
Match iOS behavior by gating the type switcher and filters menus on an
active query, and drop the .caption font so they render with the same
default button font as View Options.
Reorganize the tvOS search UI into a single header row with search
field, type filter menu, combined filters menu (sort/date/duration
with reset), and view options button. Removes the separate filter
strip between search and results on tvOS.
Unifies the filter strip on tvOS so all filters (sort, date, duration,
content type) use the same inline Menu style instead of mixing menus
with a segmented picker.
The filters sheet is too small and awkward on tvOS. Replace the filter
button with inline Menu pickers for Sort By, Upload Date, and Duration
directly in the filter strip. Applied to both SearchView and
InstanceBrowseView.
Renames YatteeServerCredentialsManager → BasicAuthCredentialsManager so the
same Keychain-backed username/password storage can be reused for any instance
type that sits behind a reverse proxy requiring HTTP Basic Auth. Adds a
one-time migration that moves existing items from the legacy
'com.yattee.yatteeserver' Keychain service to 'com.yattee.basicauth',
preserving the iCloud-sync attribute. No behavior change for end users.
On tvOS, ContentUnavailableView inside a Group doesn't expand to fill
available space — it sizes to content and aligns top-leading. Add
.frame(maxWidth: .infinity, maxHeight: .infinity) to all instances
so they center correctly in their parent containers.
The filter strip was passing the Invidious instance URL as serverURL to
AvatarURLBuilder, which built a Yattee Server-style /avatar/ path that
doesn't exist on Invidious. Now passes the actual Yattee Server URL
(matching SubscriptionsView pattern) and enriches channels from
CachedChannelData as a fallback when the API doesn't return thumbnails.
When a cancelled load task fell through to `isLoading = false`, it
created a 1-frame gap where the empty view rendered before the
replacement task set `isLoading` back to `true`. Return early on
cancellation so the surviving task controls loading state.
Move .refreshable from the outer GeometryReader onto the ScrollView
itself so SwiftUI can properly coordinate the scroll offset bounce-back.
The ScrollView was inside an .overlay() which doesn't participate in
the parent's layout system, breaking the offset reset.
Closes#917
