## Why
Clients that observe `SessionConfigured` need the same canonical
permission view that app-server thread responses provide. Reporting the
profile in protocol events lets clients keep their local state
synchronized without reinterpreting legacy sandbox fields.
## What changed
This adds `permission_profile` to `SessionConfigured` and propagates it
through core, exec JSON output, MCP server messages, and TUI
history/widget handling.
## Verification
- `cargo test -p codex-tui permissions -- --nocapture`
- `cargo test -p codex-core --test all permissions_messages --
--nocapture`
