[DRK-133] Split AuditLogAttribute XML doc: move property-level behaviour into remarks

[baoduy]

Doc-only change: split AuditLogAttribute's XML doc so the class-level and property-level meanings each get their own audience.

• <summary> now covers only the class-level meaning (entity inclusion in the audit log).
• The property-level meaning (force-plaintext under RedactSensitive, allow-listing under OnlyAttributedProperties) moved into a separate <remarks> block.

No behavioural, API-surface, or public-signature change. dotnet build -c Debug verified warning-free.

Verdict: APPROVED — docs-only change, spec-perfect, all preconditions pass.

Findings

Severity	File:Line	Finding
praise	AuditLogAttribute.cs:9-16	The <remarks> block is the correct XML doc element for supplementary detail — it renders in IDE hover tooltips alongside <summary>, giving each audience the right first sentence. Exactly matches the cycle spec.
