Add pipeline run filters bar with search functionality

[Mbeaulne]

Resolves: https://github.com/Shopify/oasis-frontend/issues/459

Description

Adds a pipeline run filters bar UI component with pipeline name search, integrated into the Home page behind a feature flag.

Note: This is a UI-only preview. The filters update the URL but are not properly connected to the API, causing a broken search state. This is resolved in a later PR in the stack.

Type of Change

• New feature

Changes

• Added PipelineRunFiltersBar component with pipeline name search input
• Integrated filters bar into Home page (Runs tab) behind pipeline-run-filters-bar feature flag

Checklist

• I have tested this does not break current pipelines/runs functionality

Test Instructions

1. Enable the feature flag: Settings → Beta → "Pipeline run filters bar (UI only)"
2. Navigate to the Runs tab on the home page
3. Verify the search input appears and updates the URL as you type (NOTE THIS WILL BREAK THE APP BUT IS RESOLVED IN LATER STACK)
