promql: fix panic with @ modifier on empty ranges (#18020) ...

When using the @ modifier with a timestamp that has no data, several
PromQL range functions were panicking with "index out of range [0]
with length 0". This was introduced by #16797 which changed function
signatures to use concrete types instead of interfaces.

The panic occurred because functions were accessing array elements
(matrixVal[0], vectorVals[0][0]) without checking if the arrays were
empty first.

Fixes #18018
