Ref: questdb/questdb#6812 - Add explicit syntax signatures for both scalar and array forms - Fix return value semantics: scalar form always produces an array when rows exist, array form returns NULL when all inputs are NULL/empty - Rename "Return type" to "Return value" to match page conventions - Split NULL handling into its own section with per-form behavior - Add result table with real output to first example - Remove internal NaN implementation details from user-facing docs - Add backticks to SAMPLE BY references
