tvOS UX campaign polish (TV1, TV3, TV5, TV6):
- Invidious sign-in asks for a Username, which is what it verifies;
the wire field is still called email, noted where it is sent
- Video counts pluralize ("1 video"), via catalog plural variations;
the two-argument count-and-duration key uses fully positional
substitutions, since a mixed format made CFRetain fault on the
integer argument (TV10)
- Character counters render their limits verbatim ("0/1000"), here
and in the preset-name and bookmark-note counters with the same bug
- Deleting a playlist, local or remote, names the playlist the way
removing an account already named the account
Render the macOS control bar button row and top bar from the active
preset's sections via a new MacOSControlsSectionRenderer, replacing the
hardcoded QuickTime-style rows in MacOSControlBar. Add a keepOnTop
button type and macOS-specific button availability lists, and adapt the
player controls settings editors (preset editor, section editor, button
configuration) for macOS.
Also apply the preset font style to the control bar time labels, and
update the built-in macOS Default preset order (queue before transport,
fullscreen at the end), bumping builtInPresetsVersion to 7.
Add macOS-only minimum frame sizing to sheets that wrap a
NavigationStack/Form without intrinsic size, so they render properly
instead of collapsing to just the toolbar. Affects Customize Home,
subscription/channel view options, playlist create/edit, search
filters, media browser options, instance picker, log filters, preset
editor, and legacy data import result.
