fix(enterprise): diagnostics list-checks returns 404 against local Enterprise demo cluster

[joshrotenberg]

Summary

redisctl enterprise diagnostics list-checks currently returns HTTP 404 against the local Enterprise demo cluster.

Reproduction

Against the local demo stack on https://localhost:9443:

redisctl enterprise diagnostics list-checks --profile local-enterprise

Observed result:

• HTTP 404 from the underlying API call

Expected behavior

One of the following should be true:

• the command targets the correct live endpoint and succeeds, or
• the command detects that this operation is not supported by the current Enterprise version and returns a clear version/feature-specific error

Why this matters

A 404 here likely means one of:

• wrong endpoint path
• stale API assumption
• feature not present in the demo version without clear handling

We should not leave this as an opaque failure in a command that otherwise looks supported.

Acceptance criteria

• Reproduce against the local Enterprise demo stack
• Determine whether the endpoint path is wrong or unsupported for the demo version
• Fix the handler or improve the error reporting accordingly

Context

Found during live Enterprise integration testing.
