Marc-André Bombeck fe13fa966b fix(labs): print range bars and lab values in the reader's number format
Range bars and the lab list, detail rows, chart tooltip and reference
ranges printed numbers with a plain `String()`, so a German reader saw
"1.8 mIU/L" and "61.3 kg" under a German interface. The same was true
of the mean, GMI, eA1C and the advanced indices on the glucose panel.

`RangeBar` now prints value, bounds and delta through the locale number
formatter and takes an optional `formatValue` for surfaces with their
own precision. Lab values keep their trim rule (whole numbers bare, at
most two decimals) in `formatLabValue`, which now hands the digits to a
caller-supplied locale formatter; `useLabNumber` wires it to the
reader's locale for every lab surface. Inputs are unchanged.

/**
* The reference window a reading's own report printed, shown wherever that
* reading is shown.
*
* Renders nothing for a reading with no printed window — most of them — so it
* costs no space on the common row. When the report DID state a window it
* names it, verbatim where the report gave words; and when that window and the
* catalog band disagree it names the catalog band too. A reader told only
* "3,9–5,4" and a reader told only "3,5–5,0" draw different conclusions from
* the same number, so a surface that shows one silently is showing a partial
* answer.
*
* Neutral by construction: no tint, no icon, muted text. The in/out verdict is
* the badge's job — this element states where the window came from, nothing
* about whether the value is good news.
