Feat: Add Create and Update capabilities to TUI

Introduce the ability to create or update resources in a TUI schema driven form. We have the existing TUI which is organized by resource types. We could provide a keyboard shortcut to launch a form which is driven by the schema of a resource type, allowing users to quickly enter values and press 'Enter' to submit a Create request. Same for updating an existing resource when one is highlighted and selected, we could present a schema driven form to update the values and submit on 'Enter'.

Right now the tui is launced with `kongctl view` implying a readonly view. We might want to introduce instead `kongctl explore` or `kongctl manage`. We could add a `read-only` mode to the TUI and set that view the existing `view` command (YMMV).

Start by reading the existing TUI launched with `kongctl view` and how it is organized by resource types. The issue does not name implementation files or tests; clarify the schema-driven form, keyboard shortcuts, command naming, read-only behavior, and create/update completion criteria before coding.
