feat: refine table editor insert zones, square headers, pointer cursors

Insert zone improvements:
- Row insert: hover zone now only covers the row-number area (left edge)
  instead of spanning the full row width, matching the column insert
  pattern where the zone is between header cells. The + button is
  positioned at the intersection of the horizontal row border and the
  vertical first-column border (translate-x-1/2 on the right edge of
  the row-number cell).
- Column insert: blue highlight line now extends through the entire
  table (header + all data rows) using bottom: -200rem with
  pointer-events-none so it doesn't block cell interactions.
- Row insert: blue highlight line extends across the full table width
  using width: 200rem with pointer-events-none for the same reason.
- Removed the spacer <tr> approach for row inserts; zones are now
  directly inside the row-number <td> with absolute positioning.

Visual changes:
- Headers are now square (removed rounded-tl-md from header cells and
  rounded-bl-md from last-row cells).
- All buttons have explicit cursor-pointer class (sort, delete column,
  delete row, add column, add row, insert column, insert row, cancel,
  confirm, and the + insert buttons).
