✅ The formula editor accepts the formulas it always ran

If you build calculated custom fields, you may have hit this: a formula that computes correctly still showed as invalid in the editor, so the preview refused to run.

The editor now understands the full formula syntax, including:

• Lists — SUM([${itemEstimate}, ${itemLikelyEstimate}]), CONCAT([${itemTitle}, ${itemNumber}]). This is the form most functions use for a range, and it is what the built-in examples insert when you pick a function from the suggestions.
• Decimals — 0.5 * ${itemEstimate}.
• True/false and empty values — IF(true, 'Yes', 'No'), COUNTA([1, null, 3]).
• Text with escapes — apostrophes and line breaks inside quoted text, such as 'it\'s ready'.

Existing calculated fields are unaffected: every one of them computes exactly the same value as before. This corrects what the editor would accept, not what a formula means.
