ui: generate a profile from a card snapshot

- new 'Profile from snapshot' button in the Profiles toolbar: reuses the
  snapshot picker (profilerSnapshotPickListHtml refactor) and then opens
  the same scan form as Profile from card (profilerScanOpenForm), with
  the profile name prefilled from the snapshot
- new profiler-build target 'profile-snapshot': the form's ignore list,
  mask options and FCP/FCI mode apply to profilerScanSnapshot(), which
  walks the snapshot's captured files instead of the card; uncaptured
  contents produce rules without a content check, record files map to
  exact record content, transparent files honor the masks
- profilerScanStart() pushes the generated profile and opens the editor
  like the live scan; _scanSnapshot is cleared in the finally block
- RU entry 'Профиль из снимка'; tests for the snapshot rule builder
  (exact/mask/ignore/uncaptured/record), the snapshot scan progress, the
  picker wiring and the form title, plus a structural button check;
  help EN/RU and READMEs updated; SW cache v130 -> v131.
