ui: compact FCI rows in the file manager (v2.7.11)

- The short file identifier is merged into the File identifier row
  (same row, ' · ' separator) in profilerFciPreviewItems, everywhere the
  decoded FCI is rendered.
- New hideFileSize option: pysimFsInfoHtml drops the FCI File size row
  when its own header already shows Size (kept otherwise, e.g. DFs).
- tests: merged SFI row, hideFileSize, header-size precedence.
