Previously the modal's aside was gated on `focusedPhotoQuery.data`, so
each arrow-skim unmounted the sidebar until the next photo's metadata
arrived — which reflowed the preview pane sideways. Now the aside is
always mounted while the modal is open; its contents swap between the
metadata panel and a small InlineLoader the same way the timeline's
right-aside does.

Preview pane paints instantly: a blurred copy of the same thumbnail the
grid loaded (cache hit) rides beneath the sharp fit_1280, which now
carries fetchpriority=high and decoding=async. A $effect prefetches
fit_1280 for the ±2 neighbours so arrow-skim hits the HTTP cache.
Carousel thumbs drop to fetchpriority=low so they yield to the main
image. Skeleton grid gains an mt-2 to breathe against the toolbar.
BulkActionBar moves inside the main column in both PreviewModal and the
/tags drill-in so it no longer stretches under the right sidebar.

The old SplitGrid + InlinePreview pane is replaced by a full-screen
PreviewModal mounted once at the layout root. Open via Space on the
focused tile or double-click; close on Esc (or X / Space again).
Inside, PreviewPane renders the focused photo, RightSidebar carries
the metadata, BulkActionBar reuses the existing per-photo actions,
and PreviewCarousel windows ±50 thumbs around the focused index.
Selection contract matches the grid: plain click reduces, shift
extends the range, ⌘/Ctrl toggles, plain arrow drops the multi-
selection, shift-arrow extends. New clearBulkToFirst() helper makes
Esc / Clear collapse a bulk back to single-focus on its first member
before the next press fully dismisses (modal closes, grid clears
focus).
Tags route reorganised into /tags/[category]/[[value]] with its own
+layout and TagsBrowserSidebar; the old monolithic /tags/+page is
trimmed to a legacy redirect.
