* fix: flush stream after write_all in hyper_client proxy

Add explicit flush() calls after write_all() for TLS stream, plain TCP
stream, and CONNECT tunnel requests to ensure buffered data is sent
immediately, preventing connection hangs in Copilot auth header flow.

* style: fix cargo fmt formatting

* Fix Copilot dynamic endpoint handling

* fix: restore clear_auth() memory-first cleanup order and fix cache leaks

- Restore clear_auth() to clean memory state before deleting the storage
  file. The previous order (file deletion first) caused a regression where
  users could get stuck in a "cannot log out" state if file removal failed.

- Add missing copilot_models.clear() in clear_auth() — this cache was
  cleaned in remove_account() but never in the full clear path.

- Add endpoint_locks cleanup in both remove_account() and clear_auth()
  to prevent minor in-process memory leaks.

- Update test to assert the correct behavior: memory should be cleaned
  even when file deletion fails.
