chore(audit): ScadaBridge C7 — perf re-baseline + CollapseAuditLogToCanonical projection test + index-test fix + dead-cref cleanup (Task 2.5)

Browse Source 
Perf re-baseline (HotPathLatencyTests): empirical p95 on Apple M-series Release
build: 4KB DetailsJson slow path ≈14 µs, small-DetailsJson no-redactors ≈2 µs,
true no-op fast path ≈0 µs. Thresholds updated: 200 µs / 30 µs / 5 µs (≈15×
headroom for contested CI runners). Old thresholds (50 µs / 10 µs) were set for
the pre-C3 typed-field path; canonical JSON parse+rewrite is empirically faster.
Adds a third test (Filter_Apply_NoDetailsJson_FastPath) that asserts same-instance
return on the DetailsJson-null + within-cap fast path. Env-var overrides retained.

CollapseAuditLogToCanonicalMigrationTests (new): three MSSQL-gated [SkippableFact]
tests verifying Action/Category/Outcome projection, NULL Actor, DetailsJson codec
round-trip, and all six persisted computed columns (Kind/Status/SourceSiteId/
ExecutionId/ParentExecutionId) for ApiOutbound, InboundAuthFailure, and Failed-
status rows.

AddAuditLogTableMigrationTests: rename CreatesFiveNamedIndexes →
CreatesNineNamedIndexes; expand coverage from 5 original indexes to all 9 named
non-clustered indexes present after CollapseAuditLogToCanonical (adds
IX_AuditLog_Execution, IX_AuditLog_ParentExecution, IX_AuditLog_Node_Occurred,
UX_AuditLog_EventId).

Dead-cref cleanup: zero references to the deleted IAuditPayloadFilter /
DefaultAuditPayloadFilter / SafeDefaultAuditPayloadFilter types remain in any
.cs file (source or test). 26 occurrences across 13 files replaced with correct
references to IAuditRedactor / ScadaBridgeAuditRedactor / SafeDefaultAuditRedactor
or reworded as plain prose.

Residual sweep: no unused transitional code found beyond the acknowledged
"C3 transitional shim" comments on IngestedAtUtc stamping (active code, not dead).
