fix(cosmosdb): correct operator precedence and function name casing

Split binary_operator into precedence-tiered rules (multiplicative,
additive, shift, comparison) and reorder scalar_expression alternatives
so AND/OR have lower precedence than comparison operators. Previously
AND/OR bound tighter than =, >, < which caused incorrect parse trees.
Also fix STRINGTONUMBER to StringToNumber for consistency.
