feat(table_core,virtual_table): Propagate injection info on commit

RowCommitInfo now includes:
- is_injected: bool (was this an injected row)
- injection_index: ?usize (where it was injected)

buildCommitInfo() copies these from RowEditBuffer.

VirtualAdvancedTable sets result.injection_committed and
result.injection_row_idx when committing an injected row,
for both Tab navigation and selection change commits.

This allows the panel to know when to INSERT vs UPDATE and
handle the special case of locally injected rows.
