fix: snapshot/profile scans skipped DF subtrees (parent_path off-by-one)

profilerScanCard's walkDir passed each child dir's own segment in
parent_path (dir.parentPath.concat(childSeg) as the child's parent path),
so /api/tree for every DF child walked the target as its own parent and
failed: DF.GSM, DF.TELECOM and DF.GSM-ACCESS subtrees were silently
missing from New snapshot, Profile from card and Profile from snapshot
(ADF children survived only because application names/AIDs resolve
globally).

- walkDir now stores each dir's full path and sends
  parent_path = fullPath.slice(0, -1) (omitted for MF); the child's full
  path is fullPath.concat(aid/fid/name)
- verified against the running server: the walker now enumerates 189 EFs
  and captures 92, matching the file-manager probe exactly (was 111/48)
- test: fake MF -> DF.GSM tree asserts parent_path [undefined, ['MF']]
  and that both subtrees' rules are produced; SW cache v132 -> v133.
