Inbound-API bearer credentials are no longer persisted in plaintext. ApiKey now
holds a KeyHash (peppered HMAC-SHA256); the key is shown once at creation and
only its hash is stored. Lookup and validation hash the presented candidate.
Cross-module: Commons (ApiKey, ApiKeyHasher), ConfigurationDatabase (mapping +
HashApiKeyValue migration), InboundAPI (ApiKeyValidator), ManagementService
(key creation), CentralUI (ApiKeys.razor). Existing keys must be re-issued.
Establishes a per-module code review workflow under code-reviews/ and
records the 2026-05-16 baseline review (commit 9c60592): 241 findings
across all src/ modules (6 Critical, 46 High, 100 Medium, 89 Low).
This is the clean starting point for remediation work.
