refactor(ui): move mosaic clerk features under features/

[alexcarpenter]

Description

Groups the Mosaic surfaces that connect to Clerk data under packages/ui/src/mosaic/features/, next to reverification/, so the Mosaic tree reads as features/ (Clerk-connected flows that own a machine), blocks/ (reusable view fragments), and components/ (design-system parts).

• mosaic/user-button/ and mosaic/user-profile/ move to mosaic/features/.
• reverification/panels/ becomes reverification/steps/, since each file is one step of the Flow.
• The three account and delete section controller tests move to features/user-profile/__tests__/, matching how reverification keeps one test file per layer.
• Relative imports were rewritten before the move so every specifier still resolves. Swingset story imports and source: paths follow the new locations, and the Reverification story leaves the Blocks sidebar group for its own group beside User Button and User Profile.
• The mosaic skill and references/mosaic-architecture.md only get path substitutions here. Placement rules for the new layout land in a follow-up PR.

No exported API changes. Everything moved is internal Mosaic source.

📝 Walkthrough

Walkthrough

The change aligns Mosaic implementation, test, story, fixture, and documentation paths with the features directory structure. It updates relative imports across user-button and user-profile modules. Swingset stories and source metadata now reference the relocated modules. Reverification imports now use steps, and registry ordering places reverification before destructive entries. An empty Changesets frontmatter block was added.

Priority: ⬇️ Low

Estimated code review effort: 2 (Simple) | ~15 minutes

Merge Risk: 🔵 Low · up to acb55

The migration remains low risk, but the architecture guide should be corrected because its conflicting paths can direct future Mosaic work to the wrong location.

Use a real Clerk instance or rename this test.

This .integration.test.tsx file renders UserProfileProfilePanelView with vi.fn() callbacks. It does not use a Clerk instance. If this test only verifies view behavior, rename it to a view test. Otherwise, mount the real Clerk integration and assert the callback flow through it.

As per coding guidelines: “Use real Clerk instances for integration tests.”
