ui: show the provider in the eSIM profile card title

The card title showed only the nickname or profile name ('0002'); with
the provider in front it reads 'Alfa 0002' and still prefers a user
nickname ('Alfa Work') when one is set.

- esimProfileTitle(): provider + (nickname || name), falling back to the
  ICCID and finally '?'.
- tests for the helper; help EN/RU and sw.js simple-v234.
