file manager: path-based selection + ADF AID normalization

Make the DF context from the resolver actually reach the live views:

- pysimFsSelected now stores the canonical path (pysimFsNodePath), not
  the node name; pysimFsRenderNode emits the path in the click/toggle
  handlers; every consumer resolves via pysimFsFindNodeByPath.  The
  name-based pysimFsFindNode is removed - two same-named files under
  different DFs (EF.ECC/EF.AD, DF.PHONEBOOK copies) are now distinct.
- efDfFromPath maps ADF-rooted parent segments by RID (A0000000871002
  -> ADF.USIM, A0000000871004 -> ADF.ISIM), so snapshot/profile paths
  rooted by AID resolve to the same DF key as the named form.
- efDecEcc shares efEccCategory with efDecEccUsim (TS 24.008
  Table 10.5.135d), so the SIM and USIM category displays can't drift.

Frontend 1087 + Python 1090 tests green.  (Version/sw bump deferred -
  this is part of the unreleased decoded-editing batch.)
