Ed L 0cb491901d fix: formula correctness and command validation bugs

- model.rs: division by zero now returns Empty instead of 0 so the cell
  visually signals the error rather than silently showing a wrong value.
  Updated the test to assert Empty.
- parser.rs: missing closing ')' in aggregate functions (SUM, AVG, etc.)
  and IF(...) now returns a parse error instead of silently succeeding,
  preventing malformed formulas from evaluating with unexpected results.
- dispatch.rs: SetCell validates that every category in the coords
  exists before mutating anything; previously a typo in a category name
  silently wrote an orphaned cell (stored but never visible in any grid)
  and returned ok. Now returns an error immediately.
