chore: refactor to directly create Client in Command Handlers (#19760)

Refactors the CLI to create the `*codersdk.Client` in the handlers. This is groundwork for changing the `rootCmd.InitClient()` to use the new `ClientOption`​s.

It also improves variable locality, scoping the Client to the handler. This makes misuse less likely and reduces the memory allocations to just the command being executed, rather than allocating a Client for every command regardless of whether it is executed.
