Problem

With the cursor on the line above a table and nothing selected, choosing
Styles > Miscellaneous > Boxes > Box crashes BrailleBlaster:

FormatterException: An error occurred while reformatting
Caused by: NullPointerException: No brl found
  at TextRenderer.appendToView(TextRenderer.kt:119)
  at TextRenderer.addTable(TextRenderer.kt:128)

Cause

TableSelectionModule only marks a table as selected when there is a
range selection, so with just a cursor updateStyle skips the branch that
resolves the original table and detaches its formatted copy.
StylesMenuModule.boxBlock then wraps only the table copy (or one of its
cells), leaving the original table outside the box. On reformat, the
stale copy has no brl and the text renderer throws.

Fix

boxBlock now resolves the node to its owning original table and
detaches the table copy before wrapping, matching the selection-based
path. This also applies to Color Box. With the cursor inside a table cell
and nothing selected, Box now wraps the whole table instead of that cell.

Testing

• brailleblaster-core compiles.
• Not yet verified in the running app. The SWTBot UI tests do not start
  on the Windows dev machine, and the existing Box UI tests are disabled.
• Manual check: open a document with a simple table, put the cursor on
  the line above it, and apply Styles > Miscellaneous > Boxes > Box. The
  box should surround the whole table without a crash.
