Redesign the selection action bar to remove horizontal scrolling

The multi-select action bar (Files/Photos/Favorites) hid bulk actions
behind a horizontally-scrolling row with no visible cue that there was
more to find, once there were more than a handful (up to 9: favorite,
share, download, delete, copy, move, rename, sync, details).

Designed the replacement on the linked design canvas first (Selection
action bar boards), then implemented it: NooSelectionBar now shows a
fixed number of actions inline (3 on mobile, 4 on desktop) with the rest
behind a trailing "More" button that opens the same overflow sheet a
file row's own "..." menu already uses. Removed the now-dead
scroll-hint plumbing from the three screens that render it.

+- Desktop: inline actions are labelled tonal pills (accent-soft/

+  has the room for labels, and the app's other toolbar actions are already
+  labelled buttons rather than bare icons. "More" is a secondary pill
+  (surface-2/fg-1) with a trailing `chevron-down`, so it reads as "opens a
+  menu" rather than another bulk action.

 **Grid card**
 - Surface fill, radius 18. Mobile uses 2 columns with a 10px gap; desktop uses 5 columns with a 16px gap.
 - The thumbnail area is 104–118px tall, filled with the file-type soft color and a 32px icon. Real thumbnails replace it when they exist.

+///
+/// A `surface` card (radius 20) - selection reads as a distinct mode, not
+/// just a row of buttons floating on `bg` - with a close circle, the
+/// count, and the bulk actions. This sits in the *content* pane's own
+/// pinned header slot on every platform (the shell's desktop toolbar,
+/// built separately in `main.dart`, never changes for selection), so
+/// mobile and desktop share the same fixed 56px height; only the gutter
+/// ([isDesktop] ? 24 : 12, matching `NooLayout.gutter`) and the actions'
+/// presentation differ:
+/// - Mobile: the first [_kMobileInlineActions] actions as plain 20px
+///   accent-text icons, no fill.
+/// - Desktop: the first [_kDesktopInlineActions] as labelled tonal pills -
+///   danger-soft/danger for the one labelled "Delete", accent-soft/
+///   accent-text otherwise - since desktop has the room for labels.
+///
+/// Any actions beyond that inline count sit behind a trailing "More"
+/// button that opens the same grouped-list sheet a file row's own overflow
+/// menu already uses (see `FilesView._showItemActions`) - never a second
+/// scrolling row, which is what this replaced: with up to 9 bulk actions
+/// (favorite, share, download, delete, copy, move, rename, sync,
+/// details), a horizontally-scrolling row hid actions behind a swipe
+/// gesture with no visible cue that there was more to find.
