When a user authenticated successfully but was not on the MCP whitelist,
the MCP server returned an opaque "MCP access denied" 403 — the user could
not tell why auth was interrupted or that they simply needed to be
whitelisted by the server owner.
- access-guard: distinguish a genuine authorization denial (not whitelisted)
from an infrastructure failure (backend unreachable / malformed) via a new
infraError flag on AccessCheckResult. Only a genuine deny gets the
user-facing "User not enabled for MCP usage" error plus an actionable
message naming the account and pointing at the fix (ask to be whitelisted).
Infra failures keep a neutral "MCP access check unavailable" message so the
user is not sent chasing the wrong fix. The reason field still echoes the
backend reason verbatim.
- backend McpUserService: WhitelistOnly denial reason is now self-explanatory
("User not enabled for MCP usage (account is not on the MCP whitelist)").
- tests: cover the actionable whitelist message and that an infra failure is
not mislabelled as a whitelist problem.
