Normalize DateFormula article sections

Browse source 
Keep the analyzer-gap explanation in Description and its scoped probe evidence in References, without a novel Validation section. Normative guidance and fixtures are unchanged.

## Description ## Description
A `DateFormula` stores a formula in a language-independent representation, but `Evaluate` must first interpret its text input. Declaring the destination as `DateFormula` does not make an English literal such as `1W` independent of the session language: French uses `S` for weeks. Passing the resulting typed variable to `CalcDate` does not repair a parsing failure that already happened in `Evaluate`.

## Validation
Exercise the default path with an empty formula and an explicit reference date in English and a language with different unit tokens, such as French. Both should produce a date one week later. Also cover an already configured formula and input entered in the active language; these must retain their meaning.
