Files view: the change-details modal shows the full file path (v2.4.2)

- the modal header showed only the flat name (EF_ICCID, 4F09); it now shows the
  path built from data already available: the tracker's DF identity named via
  KNOWN_FIDS (MF, DF_GSM_ACCESS, DF_TELECOM, …), 'ADF' for the current
  application (7FFF), DF_CHILDREN for DF-qualified EF names (4F52 →
  EF_KcGPRS) and the EF.DIR labels for AID-selected applications —
  e.g. `MF/EF_ICCID (2FE2)`, `ADF/EF_IMSI (6F07)`,
  `DF_GSM_ACCESS/EF_KcGPRS (4F52)`, `AID A00000015141434C00/4F09`
- exposed as `path` in the change-details payload and in the files entries
  (the timeline rows keep the short name — they have no room)
- the colour legend (changed / newly observed / never observed) moved below
  the two hex views
- tests: `_file_path` cases (MF, ADF, DF-qualified EF, AID with and without an
  EF.DIR label, FID-as-name) plus the payload field, and the Node modal test
  asserts the path header and that the legend follows the views
- v2.4.2; SW cache simtrace-analyser-v68
