Fixes #5494

Description

Pagination control was not showing surrounding page numbers when navigating to later pages. Fixed by enabling rotate on the ngb-pagination component so it centers the active page within the visible range.

Instructions for Reviewers

List of changes in this PR:

• Set [rotate]="true" on ngb-pagination in pagination.component.html
• Added rotate = true as default value in PaginationComponentOptions for consistency
• Added unit test in pagination.component.spec.ts to verify surrounding pages are shown when navigating to a later page

How to test:

1. Open a paginated list with many pages (e.g. Search results)
2. Navigate to page 10
3. Verify the pagination control now shows surrounding pages: « 1 ... 8 9 [10] 11 12 ... N »

Hi @lgeggleston ,

Frontend tests pass successfully (5821/5821).

CI is failing when starting the DSpace REST backend via Docker:

"no matching manifest for linux/amd64" (dspacesolr image)

This appears to be unrelated to this PR and likely an upstream CI/Docker issue.

@guillermo-escire thanks! Yes, looks like there was just an unrelated failure on the last backend Docker image build, so I'll re-run the tests when that's fixed.
