Add work-request status command

[Jaytee-fn]

The change adds a consolidated CLI command for inspecting function lifecycle work requests.

This PR introduces a simplified work-request inspection experience through:

• fn work-request status
• fn work-request status --app

The command consolidates the most relevant information into a single view:

• work request id
• function name
• operation
• status
• latest error
• recent logs

The PR includes -

• add work-request top-level command
• add status subcommand
• support resolving the latest work request for a function by app + function name
• display consolidated status/error/log output
• support direct work request id inspection, including OCI Functions work request OCIDs

fn work-request status --log-limit 20

fn work-request status hello --app --log-limit 20
