Summary

Summarize the changes made in this pull request. Include any relevant context or background information that would help reviewers understand the purpose and scope of the changes.

Release Impact

Pick the target branch (see RELEASES.md for the full model):

• dev — internal testing → publishes to ppa-build-dev
• main — next beta → publishes to ppa-build
• release/YY.MM — point release on a maintained cycle → publishes to ppa-build-YY.MM (and to ppa-build-stable if this is the currently-promoted branch). Specify cycle: release/____

Change type (tick one):

• Patch (fix)
• Minor (feature)
• Major (breaking)

The change-type label is informational and only affects how the entry is rendered in the CHANGELOG. The actual version is computed from the branch and CalVer cycle — pnpm changeset's patch/minor choice does not influence it.

Checklist

• Changeset added — I have run pnpm changeset (or pnpm changeset --empty if no CHANGELOG line is warranted) and committed the resulting .md file. Required for PRs targeting main and release/*; enforced by the Changeset check workflow.
• UI verified — I have verified the changes locally.
• Linting clean — No linting errors are present (especially in scripts/).

Versioning Reminder

Important

Landscape UI uses CalVer (YY.MM.Point.Build). Version derivation by branch:

• main / point/* → YY.MM.0.<run>-beta
• dev → YY.MM.0.<run>-dev
• release/YY.MM → YY.MM.1.<run> (cycle pinned by branch name)

Pull request overview

This PR refactors publications-related UI in Mirrors (and Local Repositories) to reduce duplicated API hook implementations by reusing the Publications feature’s query hook(s) and introducing a shared AssociatedPublicationsCount component.

Changes:

• Added AssociatedPublicationsCount to centralize “publications count + link” rendering for any source name.
• Updated Mirrors and Local Repositories lists/modals/forms to use shared publications hooks/components, removing mirrors-specific useListPublications / useListPublicationTargets hooks and the MirrorPublicationsLink component.
• Simplified/standardized conditional rendering around publications association messaging in remove flows.

src/features/publications/components/AssociatedPublicationsCount/AssociatedPublicationsCount.tsx:16

• AssociatedPublicationsCount fetches all publication pages via useGetPublicationsBySource (which loops over nextPageToken). Rendering this component in lists (mirrors/local repositories) can cause N+1 network traffic and long blocking spinners for sources with many publications. Consider a dedicated hook for counts that only fetches the first page and shows a limited count (e.g. 3+) when nextPageToken is present, or otherwise avoid per-row full pagination.
  src/features/mirrors/components/PublishMirrorForm/PublishMirrorForm.tsx:60
• If publicationTargets is empty, the "New publication" path renders PublishMirrorNewForm with no target options, which can leave the form in an unusable state (required select with no options). Guard the render so the new form is only shown when targets exist (and fall back to the existing-publication form when possible).

        {useNewPublication ? (
          <PublishMirrorNewForm
            mirror={mirror}
            publicationTargets={publicationTargets}
          />
        ) : (
          <PublishMirrorExistingForm
            mirror={mirror}
            publications={publications}
          />
        )}

LGTM, one suggestion and a comment on what may be a slight regression in error reporting.
