An MSL 00 TAR without a default keyset is a legitimate keyless entry, but
_resolve_operation_keyset left the request's KIc/KID empty and the RAM /
APDU builds failed with "invalid literal for int() with base 16: ''".
The resolution now fills the spec's no-security 00/00 KIc/KID form for a
preset entry without a keyset, and refuses a TAR outside the preset with
a hint (the old silent '25' default was arbitrary). The PWA's TAR change
resets the form the same way - a stale previous TAR's KIc/KID would
otherwise travel explicitly and build a non-keyless packet.
Also: the dead _preset_tar_keyset helper removed; tests for both keyless
paths. 892 frontend + 886 Python; sw cache simple-v435.
