Paste Name and Go To: follow-ups from the batch review (#2540)

* Go To: names match in any case and script, as formulas match them

* Paste Name: only the names in view are laid out

* Docs: LAMBDA recursion limit and called error names; one Page Layout view row with the side margin marked unverified

* Go To and Paste Name: cargo fmt

Difference: BYROW/BYCOL pass their row or column to the LAMBDA as values, so `BYROW(A1:B3,LAMBDA(r,EOMONTH(r,0)))` lifts where Excel gives `#VALUE!` |

Calling a defined name that holds an error value gives that error, not `#NAME?` |
 | Iterative calculation for circular references | done: with Enable Iterative Calculation on (`formulas.calculationOptions` `{iterative, maxIterations, maxChange}`, saved as `<calcPr iterate iterateCount iterateDelta>`), loops are evaluated again from their previous values (blank = 0) until no cell on a loop changes by Maximum Change or Maximum Iterations is reached; off, cycles give `#CIRC!`. Differences: no Options dialog yet (command only); GridCraft recalculates on open, so a loop that never settles (`=A1+1`) advances again each time the file is opened |
 | 15-significant-digit comparison semantics | done (#57): `=0.1+0.2=0.3` is TRUE, and MATCH and COUNTIF compare the same way. Arithmetic keeps full precision, as Excel does — `=(0.1+0.2)-0.3` is 5.55E-17 |
