fix: preserve matrix data for range refs in function infix expressions

When a range token (e.g. Ledger!H:H) was the first operand in an infix
expression inside a function argument (e.g. IF(Ledger!H:H="TRANSFER",...)),
there was no handler for the case where nextToken is an infix operator.
The range fell through to parseToken which converted the ArgMatrix to a
scalar string via formulaArgToToken, losing all matrix data.

This caused formulas like MAX(IF(Sheet!Col:Col="X",ABS(Sheet!Col:Col)))
to always return 0 because the column reference was reduced to its first
cell value before comparison.

Add a condition in evalInfixExp to parse the reference directly and push
it to opfdStack when a range token inside a function is followed by an
infix operator, preserving the full matrix data for element-wise operations.
