Oliver Kieselbach 6e54b52376 backend: migrate the 458 anonymous error bodies to the typed envelope helpers ...

Every non-2xx body in the Functions project now goes through ResponseHelper
(ErrorAsync / BadRequestAsync / NotFoundAsync / ForbiddenAsync /
UnauthorizedAsync / ConflictAsync / InternalServerErrorAsync): 408 sites by a
pattern-exact rewrite of the CreateResponse + WriteAsJsonAsync + return shape,
50 by hand. The eight private BadRequestAsync shadow helpers are gone; the raw
500 catch blocks use InternalServerErrorAsync (sanitized message, correlation
id, MCP hint). 429s keep Retry-After via retryAfterSeconds.

Specialised error bodies where a consumer reads more than the prefix:
AppHomingDeniedResponse (kebab reason codes now Constants.AppHomingReasonCodes,
probe result), TenantConfigPatchFailedResponse (backupId, drift),
QueryBackendLogsErrorResponse (upstreamCode, statusCode, source, hint,
upstream). Twenty-one message-first 200 bodies that the old error tolerance had
let through are typed too (MessageResponse, PreviewWhitelistActionResponse,
SuccessMessageResponse). New codes: PayloadTooLarge, UpstreamError,
UpstreamTimeout, the three trial-gate codes; the agent security path
(SecurityValidationExtensions) writes the envelope with the retry window.

TypedResponseGuardTests: WriteBaseline is empty again — the anonymous
WriteAsJsonAsync ratchet now covers error bodies with zero tolerated sites.
Manifest and generated TypeScript regenerated.
