Remove duplicate/internal fields from UI config schema

Fields like model, reasoning effort, instructions file path, max turns,
timeout, and grace period are either surfaced elsewhere in the platform
UI or are internal operational settings that shouldn't be user-facing
in the adapter config panel. These values remain functional when set
via the API/backend — only the UI exposure is removed.
