ROX-31807: Adding Analytics for Base Images

[sachaudh]

Description

Add analytics tracking for the Base Images feature to measure adoption, engagement, and friction points.

Events added:

• BASE_IMAGE_REFERENCE_ADD_MODAL_OPENED - tracks user intent
• BASE_IMAGE_REFERENCE_ADD_SUBMITTED - tracks form submission attempts
• BASE_IMAGE_REFERENCE_ADD_SUCCESS - primary adoption metric
• BASE_IMAGE_REFERENCE_ADD_FAILURE - tracks errors with categorized errorType
• BASE_IMAGE_REFERENCE_DELETED - tracks churn

Filter tracking:

• Added Component Layer Type to searchCategoriesWithFilter to track BASE_IMAGE vs APPLICATION filter usage in Workload CVE pages

User-facing documentation

• CHANGELOG.md is updated OR update is not needed
• documentation PR is created and is linked above OR is not needed

Testing and quality

• CI results are inspected

Automated testing

• added e2e tests
• added regression tests
• added compatibility tests

How I validated my change

• Analytics events are typed and follow existing patterns (e.g., Watched Images)
• No functional changes to existing behavior; analytics calls are additive
