Bump version to v1.1.10 — guard the options-flow reload (#361)

Reported by Richardmarkink: changing a setting saved the change, then failed the
form with a bare "Unknown error", leaving the user to retry a save that had
already applied.

The options flow reloads the integration after saving. That reload was unguarded,
and async_reload() raises OperationNotAllowed when the entry is in a
non-recoverable state such as FAILED_UNLOAD — which is what happens when a poll is
wedged on an unresponsive gateway and holds the connection past the unload
timeout. The exception propagated straight to the UI.

The reload is a convenience, not part of saving: async_update_entry() has already
persisted the settings before it runs. It is now wrapped, and a failure logs a
warning stating the settings are saved and will apply after a manual reload or
restart.
