Add provider checkpoints and thread rollback support

- add provider/WS contracts and server RPC handlers for listing/reverting checkpoints - read and rollback Codex thread turns in the app server manager - add ChatView checkpoint menu + store reducer support to revert local thread state - expand backend, websocket, store, and contract tests for checkpoint flows
