fix(grid): correct autosize measurement and honour colDataTypeOf

[6pac-ai]

Summary

Fixes four faults in the grid's content autosizing (autosizeColumns() / column.autoSize). Two of them change behaviour that code may rely on, so this targets next-v6 rather than master.

Why

• autosizeColumn() did nothing visible.
• ValueFilterMode.DeDuplicate measured nothing.
• A formatter that reads other fields of its row was measured against the wrong row.
• A type supplied through autoSize.colDataTypeOf was ignored whenever the grid had data.

The docs already describe the fixed behaviour. autosizeColumn() "runs phase 1 for that column and applies the result", and colDataTypeOf "forces the data type".

Changes

1. autosizeColumn() applies its result. It computed autoSize.widthPx but never set column.width. It now sets the width and calls reRenderColumns(), re-rendering rows when the column has rerenderOnResize. It also creates the measuring canvas when autosizeColumns() hasn't run yet, instead of falling back to DOM measurement.
2. DeDuplicate measures the unique values. It bounded its loop with RowInfo.length, which is never assigned, so the bound was NaN and the column sized to its header. It now uses the number of unique values. The fallback for browsers without Object.keys is removed; it was never reached, and it had its own bug (if (rowsDict)).
3. The formatter gets the source row. Once a value filter reduces the rows to a short value list, getColWidth() called the formatter with getDataItem(i), where i is the position in that list. RowInfo gains an optional rowIndexArr, which DeDuplicate, GetGreatestAndSub, GetLongestTextAndSub and GetLongestText fill in, so the formatter receives the row and data item the value came from. The longest/greatest searches now start from the first selected row rather than row 0.
4. colDataTypeOf takes precedence. ContentIntelligent only guesses the type from row 0 when autoSize.colDataTypeOf isn't set.

Behaviour changes

• grid.autosizeColumn(id) now changes the column's width. Callers that used it only to compute autoSize.widthPx will see the column resize.
• Columns with colDataTypeOf set now use the strategy for that type even when row 0 suggests another type. For example, a 'number' column whose row 0 holds a string now uses GetGreatestAndSub instead of GetLongestText.

Validation

• New self-hosting spec cypress/e2e/quirk-autosize-measurement.cy.ts, one test per fix. With the source fix reverted, all four tests fail, each on the assertion it targets. With the fix, all four pass.
• These related specs pass on this branch:
  • quirk-autosize-colvaluearray (1/1)
  • example-auto-header-height-autosize (18/18)
  • example15-auto-resize (5/5)
  • example-grid-menu (21/21)
• tsc --noEmit, eslint on the changed files, and npm run build:prod are clean.
• The full Cypress suite was not run locally; CI covers it.
