feat: add adapter picker for imported agents

When importing a company, users can now choose the adapter type for each
imported agent. Defaults to the current company CEO's adapter type (or
claude_local if none). Includes an expandable "configure adapter" section
per agent that renders the adapter-specific config fields.

- Added adapterOverrides to import request schema and types
- Built AdapterPickerList UI component in CompanyImport.tsx
- Backend applies adapter overrides when creating/updating agents
