When the mobile label is aria-hidden and the desktop button container is
display:none (below sm:), mobile screen reader users had no aria-current
indicator. Added a sr-only span with aria-current="page" that stays in
the AT tree at all breakpoints regardless of CSS display state.
On desktop the active page button also carries aria-current — both
announce the same page information, which is acceptable.

The mobile 'Seite X von Y' span had aria-current='page', which created two
elements announcing the current page on wide screens: the hidden mobile label
and the active desktop button. On sm:+ screens the mobile span is display:none
(removed from AT tree), but on small screens both the span and the desktop
button were redundant.
Replace aria-current with aria-hidden='true' on the mobile label so AT always
relies on the desktop button's aria-current. Updates spec test accordingly and
adds a second assertion in a broader test context (Decision Queue #1).

Replaces position-based key `i` with `entry === null ? 'ellipsis-' + i : entry`
so DOM reconciliation is stable when the window shifts (Decision Queue #2).
The index-based key was masking a duplicate-push bug in pageWindow: when
windowStart === first+1 or windowEnd === last-1, the loop already included that
number, causing Svelte to throw `each_key_duplicate` once stable keys are used.
Fixed the bridge-page conditions to use first+2 / last-2 thresholds so the loop
and the bridge branches never push the same page number.

Renames 'page button buttons' → 'page buttons container' (Decision Queue #3).
Adds 'renders both pages without ellipsis when totalPages is 2' to cover the
boundary between the 1-page (hidden) and full-ellipsis-window cases (Decision Queue #5).

Adds an ellipsis-style numbered page button row (1 … 4 5 6 … 12) to
Pagination.svelte. Buttons are hidden on mobile (sm: breakpoint) and fall
back to the existing prev/next layout. Active page uses brand-navy
background. Client-side clamping via makeHref(entry - 1) satisfies AC3.
i18n key pagination_page_button added for de/en/es.
