enhancement(search): bulk actions on RepositoryCase search results

[therealbrad]

Description

Adds per-row selection on RepositoryCase hits in the global search (UnifiedSearch) plus a viewport-pinned bulk-action toolbar that surfaces two existing affordances against the current selection:

• Bulk Edit — opens the existing BulkEditModal from the repository view with the selected case ids + project id; on save the selection clears.
• Create Test Run — seeds sessionStorage["createTestRun_selectedCases"] and navigates to /projects/runs/<projectId>?openAddRun=true, the same handoff the repository view uses for its in-tab "Create Test Run from selection" flow.

Same-project gate

Selection is gated to a single project. When a selection spans projects, both action buttons are disabled with a tooltip explaining why, so cross-project selections never resolve to an ambiguous target. The selection auto-clears when the query, filters, or current-project-only scope change.

UX

The toolbar is pinned to the bottom of the viewport and matches the GlobalSearchSheet column on sm+ screens (fixed bottom-0 right-0 w-full sm:max-w-3xl); spans full-width on xs to match the Sheet behavior at that breakpoint. The search results area gets bottom padding while the toolbar is visible so the last row isn't covered.

The checkbox is only rendered on REPOSITORY_CASE hits — other entity types render unchanged. This leaves room for TestRun/Session bulk actions later without rewiring the underlying selection state.

Related Issue

N/A — internal backlog item (Brad's own pain point, surfaced 2026-06-04).

Type of Change

• Enhancement (new affordance on an existing feature)

Testing

• 6 new co-located tests in components/UnifiedSearch.test.tsx covering:
  • Checkbox visibility per entity type (cases only)
  • Toolbar appearance + count rendering
  • Cross-project selection disables both action buttons
  • BulkEditModal mounted with the correct (selectedCaseIds, projectId) shape
  • Create-Test-Run handoff seeds sessionStorage + routes to the correct project
  • Clear-selection control hides the toolbar
• Existing 26 tests still pass. The next-intl mock now substitutes the count value so plural-key assertions work, and the i18n-aware ~/lib/navigation wrapper is mocked.
• pnpm type-check clean.
• pnpm precommit (lint + format:check) clean.

i18n

• 5 existing strings reused: repository.cases.bulkEdit, repository.cases.createTestRun, common.actions.clear, repository.duplicates.selectRow, repository.duplicates.selected.
• 2 new keys under search.bulk.* for the cross-project guard wording.
• pnpm crowdin:sync propagated translations into all 13 non-English locales.

Checklist

• Code follows the project style
• No new warnings
• Tests added
• Self-reviewed
• i18n synced across locales
