Add encoder/decoder support for NotApplicableAnalysisCard (#5036)

Summary:

Add SQA storage support for the new NotApplicableStateAnalysisCard class:
- encoder.py: Add NotApplicableStateAnalysisCard check with blob_annotation='not_applicable_state'
- decoder.py: Add decoding logic for blob_annotation='not_applicable_state'

This allows NotApplicableStateAnalysisCard instances to be saved and loaded
from the database correctly.
