[client] Address the remaining bot findings on PR #7398

- Login logged the active-profile-state error and returned the same cause; the
  repo's guidelines call for one or the other, and the wrapped error is the one
  that carries context. (CodeRabbit)
- `netbird up` reported a codes.Unavailable SetConfig failure as "the daemon
  refused the settings update", but that code also covers a daemon that became
  unreachable. It now reports what the daemon said without asserting why.
  (cubic-dev-ai)
- TestLogin_ChangingTheManagementURLIsRefused asserted the error and nothing
  else, while "refused before it can touch daemon state" is the contract. It now
  checks the stored management URL, the in-progress login and the active profile,
  matching its SetConfig counterpart. (cubic-dev-ai)
