The SELECT rows (compact RFM chains and the Expanded Script C-APDU picker,
which shares the row editor) now have a file picker instead of typing FIDs,
paths or chains by hand.
Data:
- `pysim_simple_server/uicc_files.py` builds the standard file list cardless
from pySim's profiles and application classes (CardProfileUICC + CardProfileSIM
for the MF tree, every concrete CardApplication subclass for the ADFs) and
writes `frontend/uicc_files.json` (490 entries: canonical FID path, symbolic
name, fid, kind, root, ADF AID). `tests/test_uicc_files.py` regenerates it
and fails when pySim adds or renames files. The asset is precached by the
service worker, so the builders keep working offline.
Picker:
- Sources merged per canonical path: the loaded file-manager tree (card names
and probed presence; probed-absent files hidden), custom files, and the
shipped standard list (specs-default until "Probe all files" has run).
- Default list shows what the current method can express; "all files" reveals
the rest, and picking one auto-switches the method - preferring path (one
SELECT) over chain - with a note line explaining the switch. A "starts in"
selector sets the implicit current DF (UICC shared-FS RFM app starts in MF,
an ADF RFM app in its ADF, TS 102 226 7.2/7.3 - the TAR decides; default per
builder, overridable per row).
- Fill rules: by FID only for direct children of the current DF; path = FID
sequence from MF without the MF identifier (ISO 7816-4) or the relative tail
(USIM P1=09); chain stays relative and follows the TS 102 221 11.1.1.2 FID
search order (children, parent, siblings), so no hop to the common ancestor.
ADF roots are not pickable (selection is by AID; TS 102 226 7.1 forbids
P1=04 for RFM) - the By AID method stays manual.
