Context:
Following #9070 (Internal ID implementation) and the List/DataView refactor, the Grid and Table components must also be updated to support stable DOM keying.

Problem:
Grids are the primary UI for CRUD operations. Handling "Phantom Records" (newly added rows before save) is a critical use case where id: null currently causes issues.

Task:
Update Neo.grid.Container and Neo.table.Container (and their respective Views/Rows) to support internalId.

Requirements:

1. Opt-in Config: Add useInternalId config to Grid/Table Container.
2. Row Rendering: Update row generation to use store.getInternalId(record) for the <tr> or <div> ID.
3. Cell Rendering: Ensure cell IDs are derived consistently.
4. Selection Model: Update Neo.selection.grid.Model and Neo.selection.table.Model to handle internal ID based lookups.

Scope:

• src/grid/ (View, Row, Container)
• src/table/
• Selection Models
