### What problem does this PR solve?
Some BE expression and storage code creates a concrete column type and then
immediately casts the generic `ColumnPtr` or `MutableColumnPtr` back to the
same concrete type before writing data. This adds unnecessary casts and makes
the ownership intent less direct. Root cause: several local result columns were
declared as generic column pointers even though the concrete column type was
already known at creation time.
This PR refines those local variables to keep concrete column pointers where
the type is explicit, and directly accesses the concrete column data. It also
updates the explode-numbers table function member to use a concrete column
pointer. The change is limited to local refactoring and does not change runtime
behavior.
