fix: show every static DataSet member in Signal Selector

[masarray]

Problem

ARSAS v1.6.31 can discover the physical IED DataSet directory, but FCD/DataObject-level members can still disappear before the Signal Selector when no unique primary DataAttribute leaf is resolved. This is common in Siemens SIPROTEC SCL/DataSet definitions where daName is empty.

Fix

• Pin ARIEC61850 to engine PR Add Indonesian high-value IEC 61850 pages #76 / commit 52f8e383711f63d4a37af742fc92243be80aa0d6.
• Consume the new engine-owned complete DataSet selection inventory rather than only GetMandatoryPrimarySignals().
• Preserve unresolved FCD members as visible DataSet rows without guessing a leaf reference.
• Keep user selection independent (IsSelected=false).
• Mark unresolved rows explicitly as primary leaf unresolved instead of claiming a proven MMS polling target.

Regression coverage

• Siemens-like 2 DataSets / 58 FCD-only members: Signal Selector inventory must contain 58/58 rows (36 digital + 22 analog).
• Reopening the selector must not duplicate recovered FCD rows.

This closes the gap between DataSet directory discovered and DataSet member visible to the user.
