ui: group the eSIM chip info into boxes and wrap values nicely

The chip view was one long flat list spread over the full height.

- esimRenderChip split into esimChipSectionRows (object or RAT rule list
  -> rows) and esimChipBox (titled box, skipped when empty); the boxes
  are laid out on a grid: EID, EUICCInfo1, Addresses and the rules
  authorisation table in the left column, the larger EUICCInfo2 in the
  wider right-hand box (single column on narrow screens).  Rows use a
  narrower label column (w-36).
- Values wrap with break-words + min-w-0 instead of break-all: text
  breaks at spaces first and long hex/AID tokens only when they cannot
  fit (same for the profile metadata rows).
- style.css rebuilt (grid-cols-1, lg:grid-cols-3, lg:col-span-1/2/3,
  break-words).
- tests: the new helpers, the grid/box layout and the wrapping check;
  help EN/RU note the grouping; sw.js simple-v232.
