Blocks placed during /plot delete confirmation remain after plot is deleted

Server Implementation

Paper

Server Version

1.21.3

Describe the bug

When deleting a plot, any blocks that are placed during the /p confirm phase remain on the plot even after it is deleted or becomes unclaimed.
These blocks are not removed together with the plot deletion process.

To Reproduce

1. Initiate a plot deletion (/plot delete).
2. While waiting for the confirmation, place several blocks on the plot.
3. Execute /plot confirm.
4. The plot is deleted / unclaimed, but the blocks placed during the confirmation phase remain instead of being removed.

Expected behaviour

All blocks placed on the plot (including those placed during the deletion confirmation phase) should be removed when the plot is deleted or unclaimed.

Start by tracing the /plot delete and /plot confirm command entry points, then follow the plot deletion or unclaim block-cleanup path. Reproduce the sequence on Paper 1.21.3 with PlotSquared 7.5.10-SNAPSHOT and verify that blocks placed during confirmation are removed when deletion completes.
