Oliver Kieselbach 3a4d80cd7f hardening(auth): validate + audit EntraId:AdditionalClientIds trust-set expansion
Expanding the token audience trust set via EntraId:AdditionalClientIds was
completely silent: no format validation, no operator-visible logging. During
the tenant-move window a typo'd GUID would be indistinguishable from "the new
app registration doesn't work" (daily-review follow-up, 2026-07-14).

- ResolveConfiguredClientIds: additional entries must parse as GUIDs; malformed
  entries are dropped (fail-closed - they could never match a token aud) and
  reported via out param. Accepted entries are normalized to the canonical
  lowercase dashed GUID form so brace/uppercase paste variants still match the
  ordinal audience comparison. Primary ClientId handling stays verbatim.
- AuditClientIdTrustSet: one Warning per distinct config value per instance for
  (a) dropped malformed entries (truncated - never log a full pasted value in
  case it is a secret) and (b) trust-set expansion with the accepted ID list.
  Warning level because nothing below Warning reaches App Insights.
- Tests: existing ResolveConfiguredClientIds tests moved to GUID values
  (signature change, no compat alias) + rejection, primary-verbatim,
  normalization and TruncateForLog coverage.
