### What problem does this PR solve? FollowerColumnSender drains queued column references on follower FEs and syncs the columns that still need analysis to the master. A queued column can become stale after DDL changes. If the table still exists but the queued column has been dropped, table.getColumn(column.colName) returns null and the sender throws a NullPointerException while reading the type. This patch skips dropped columns before checking the column type, so the daemon does not emit periodic ERROR logs and can continue processing the remaining queued columns.
