Files view: a card-side change reads as its read, with a "Changed on card!" link (v2.6.4)

- a card-side change is discovered by a read operation, so the timeline row
  now reads "Read EF_IMSI" — the row keeps its warn colour and layout — with
  "Changed on card!" as the trailing underlined link that opens the change
  modal; an update row keeps the generic "Details" link
- the 'Changed on card' verb string is gone; the new 'Changed on card!' key
  carries the Russian «Изменено на карте!»
- tests: the verb/label cases updated (card_change -> Read, "Read EF_LOCI")
  and the Files-view wiring test pins the kind-dependent link label;
  527 Python + 61 Node tests
- README/README_RUS describe the new row wording; PWA_VERSION/pyproject/
