refactor(v1): recatalog MVP molecules and organisms

[egdev6]

Goal

Recatalog and migrate MVP components that should live as molecules or organisms under the V1 taxonomy.

Components in scope

Initial candidate list from MVP:

• Accordion
• Alert
• Autocomplete
• Breadcrumb
• Calendar
• CardContainer
• DatePicker
• Drawer
• Dropdown
• Header
• ListBox
• Modal
• Pagination
• PopOver
• Select
• Snippet
• Table
• Tabs
• Toast
• Tooltip

The inventory issue may promote or demote items before implementation starts.

Work

• Identify components that are currently mislabeled as atoms but coordinate collections, overlays, grouped controls, or data behavior.
• Split large components into lower-level dependencies plus composed molecule/organism APIs.
• Avoid private internal versions of controls that should exist independently.
• Preserve behavior while moving files and exports.
• Add migration notes for any breaking import path changes.

Acceptance criteria

• Every in-scope component has a target folder and public export path.
• Components that need lower-level dependencies list those dependencies explicitly.
• Compound/slot APIs are documented where used.
• Storybook navigation reflects the new taxonomy.
• Tests and typecheck pass after migration.
