Rename tui_app_server to tui (#16104)

This is a follow-up to https://github.com/openai/codex/pull/15922. That
previous PR deleted the old `tui` directory and left the new
`tui_app_server` directory in place. This PR renames `tui_app_server` to
`tui` and fixes up all references.

   - When extracting code from a large module, move the related tests and module/type docs toward

 - When running Rust commands (e.g. `just fix` or `cargo test`) be patient with the command and never try to kill them using the PID. Rust lock can make the execution slow, this is expected.
