Add e2e coverage for pattern wrapper block identity

[ramonjd]

What? Why?

Adds focused e2e coverage for pattern wrapper block identity after #79417.

How?

• Verifies an unsynced pattern wrapper changes its block info card badge from Pattern to Group after clicking Edit pattern.
• Verifies a pattern wrapper inside an isolated template part editor shows Header with a Group badge instead of Pattern.

Manual Testing

1. Open the post editor with a Group block that has metadata.patternName and metadata.name: "Header".
2. Select the wrapper and confirm the block info card shows Header with a Pattern badge.
3. Click Edit pattern.
4. Confirm the same block info card shows Header with a Group badge.
5. Open a template part in focus mode containing the same wrapper.
6. Select the Group block and confirm the block info card shows Header with a Group badge.

Pull request overview

Adds targeted end-to-end regression coverage to ensure pattern wrapper blocks display the underlying source block identity (name + badge) when entering pattern editing and when editing in isolated (focus mode) template part editors, aligning with the behavior introduced in #79417.

Changes:

• Adds an editor E2E test asserting the inspector block card badge changes from Pattern to Group after clicking “Edit pattern” on an unsynced pattern wrapper.
• Adds a site editor E2E test asserting an isolated template part editor shows the wrapper’s display name (Header) with a Group badge (not Pattern) for pattern wrappers.
