fix(ci): add bp-exempt to review-refire-status-tests; fix test_na_state semantics

Two fixes to get PR #1370 CI green:

1. review-refire-status-tests.yml: add `# bp-exempt:` directive on the
   test job. lint-required-context-exists-in-bp was failing because the
   new workflow emits a status context (review-refire-status-tests / test)
   without a bp-required/bp-exempt directive. The test is informational only
   (regression tests for review-refire-status.sh), so bp-exempt is correct.

2. test_sop_checklist.py: update TestComputeNaState tests to match the
   current compute_na_state return structure (declared_by/reason/valid/error
   rather than decl_ackers/rejected). Semantics: declared=True whenever a
   user posts /sop-n/a (regardless of authorization); valid=True only
   for non-author declarers who are in a required team. This aligns with
   how the main() function uses the state to build the na-declarations
   status description.
