fix(UniverSheet): keep merged cells on range move and last-column print fill

[zhaijunlei955]

Link issues

fixes #1138

Summary

Rebuild wwwroot/univer/univer-bundle.js from Univer v0.25.0 (fork 8f1ac99cb, webpack 2026-09-08).

This replaces the stock concat bundle. Runtime still loads this one file; no public C# / JS API change.

User-visible fixes

• Merged cells follow a whole-range move / cut-paste on the same sheet. A self-overlapping vertical move no longer silently drops merges; a horizontal move is no longer blocked as “across merged cells” when merges only sit on the edge of the moving block.
• Print preview no longer drops the last fully-visible column’s fill and border when the scaled viewport edge lands exactly on that grid line (text was already kept). Same for the last row in the symmetric case.
• Activating a sheet on an offscreen workbook no longer removes drawings on the visible workbook.
• Drawing cell anchors no longer pick up the current scroll offset twice (preview / design switch no longer drifts images).
• Disposing an offscreen workbook no longer kills the visible drawing Edit/Delete popup.

Out of scope

Cross-sheet cut/paste still does not move merges with the cells. That needs a separate Univer fix.

Regression?

• Yes
• No

Stock Univer 0.25.0 behavior is unchanged except the cases above. Screen rendering (non-print) is untouched by the print-range patch.

Risk

• High
• Medium
• Low

Single large asset replace (univer-bundle.js). Please smoke-test sheet edit, print preview, and any offscreen print/export path.

Verification

• Manual (required)

• Automated

• Move / cut-paste a block of row-wise merged cells up/down by one row (self-overlap): merges remain.

• Move the same block left/right when merges sit on the edge: command succeeds.

• Print a sheet whose last used column’s right edge lands on the viewport bound: last column fill and border still render.

• Batch print/export with drawings: visible images stay; Edit/Delete popup still appears afterward.

Packaging changes reviewed?

• Yes
• No
• N/A

Please bump BootstrapBlazor.UniverSheet from 10.0.15 → 10.0.16 in this PR if this should ship as a NuGet.

☑️ Self Check before Merge

Summary by Sourcery

Update UniverSheet to preserve range content, print formatting, and drawing state across sheet operations and workbook transitions.

Bug Fixes:

• Preserve merged cells when moving or cut-pasting ranges within the same sheet, including overlapping moves and edge-adjacent merges.
• Keep the final fully visible row or column fill and border in print output when the viewport boundary aligns with a grid line.
• Prevent workbook activation and disposal from affecting drawings or drawing controls in the visible workbook.
• Correct drawing anchor positioning when switching between preview and design modes.

Build:

• Update the UniverSheet package version and replace the generated Univer runtime bundle with the revised build.

Reviewer's Guide

Replaces the generated Univer 0.25.0 bundle with a forked build that preserves merges during same-sheet range moves, fixes print-preview rendering at exact row/column boundaries, and stabilizes drawing behavior across workbook visibility, scrolling, and disposal; no public C# or JavaScript API changes are introduced.

File-Level Changes

Change	Details	Files
Rebuild the generated Univer runtime bundle with targeted fixes for merged-range movement and print-preview boundary rendering.	Preserve merged-cell metadata during same-sheet whole-range moves, including self-overlapping vertical moves and edge-adjacent horizontal moves. Retain the final fully visible column or row fill and border when the scaled print viewport ends exactly on a grid line. Leave non-print screen rendering and cross-sheet merge movement unchanged.	src/components/BootstrapBlazor.UniverSheet/wwwroot/univer/univer-bundle.js
Correct workbook, drawing-anchor, and drawing-popup lifecycle behavior across visible and offscreen workbooks.	Prevent offscreen sheet activation or workbook disposal from removing drawings or the drawing Edit/Delete popup in the visible workbook. Avoid applying the scroll offset twice when calculating drawing cell anchors during preview/design transitions.	src/components/BootstrapBlazor.UniverSheet/wwwroot/univer/univer-bundle.js
