Improve Home Assistant HTTP config restart recovery

[QuinnDamerell]

Home Assistant's HTTP configuration restart can close the WebSocket before configure or confirmation responses arrive. These changes track the normalized configuration staged by Homeway so interrupted updates can be recovered without confirming unrelated user changes.

• Confirm Homeway's staged proxy configuration immediately when possible, and retry interrupted confirmation after reconnecting. Leave unrelated or rejected pending configurations for the user.
• Add bounded fast reconnect attempts for expected restarts, wake configuration retries on reconnect, release pending requests on socket closure, and ignore stale socket callbacks.
• Defer the generated WebStreamMsg import used only for typing so installer imports work from the repository root. Add configuration, WebSocket, and import regression tests to CI, with test import paths configured for Pyright.

Validation

Using an isolated Python 3.12.7 environment with the repository requirements:

• Unit tests: 18 passed; 1 Unix-only installer import test skipped on Windows.
• Pyright: 0 errors, 0 warnings.
• Ruff, YAML lint on the committed workflow, and git diff whitespace checks: passed.
• CI-equivalent Pylint invocation: all targets passed except the installer, where the existing Unix-only pwd import is unavailable on Windows.

Review note

The successful pre-restart promotion path clears ServerRestartExpected in ConfigManager._PromotePendingHttpConfig before Home Assistant's queued restart occurs. That disconnect therefore uses normal reconnect backoff instead of the new fast path. The existing regression test currently asserts that early clearing. This timing issue remains for review.

Keep fast reconnect armed until the queued restart occurs

When http/config/configure returns restart: true, the code immediately promotes the configuration, and a successful promotion reaches this call before Home Assistant's queued restart closes the socket. Clearing ServerRestartExpected here makes that imminent disconnect take the normal reconnect path in ConnectionThread—including an initial five-second backoff—instead of the newly added fast-reconnect path. Clear this state only after the post-restart connection is established or after it is known that no restart will occur.
