Subject: [PATCH] fix: mission creation for Claude Code backend

- Skip agent validation for Claude Code backend in create_mission
  Claude Code has its own built-in agents that don't exist in OpenCode's
  agent list, so validation was incorrectly failing.

- Filter model dropdown by selected backend
  Claude Code only supports Anthropic models, so the dropdown now only
  shows those when Claude Code backend is selected. Also resets model
  override when switching to Claude Code if non-Anthropic model was selected.
