Preserve manually entered HEOS host

[andrewsayre]

Proposed change

Previous change (#138950) introduced functionality to automatically update the HEOS host from discovery. This has a side-effect of overwriting a custom host name, if configured by the user.

This change introduces a new config key (manage_host: bool) and exposes it in the reconfigure screen to allow the user to toggle automatic host management (and preserve a manually entered host name). The config entry minor version was incremented and migration determines if the host name is custom (best effort) and disables the functionality. For new adds of the integration, manage_host is set to True when setup from discovery and False when setup manually.

This needs to be part of 2025.3 in order to not impact users.

I agree that this is needed. But I had this discussion already: #131066 (comment)

I guess HEOS is slightly different from Onkyo in that it has only a single config entry for the whole system composed of possibly many devices. Maybe this means an exception here would be justified.

Right, while we attempt to select the best device to connect to, it has limitations. Users with less reliable devices (some HEOS-capable products are flakey), or batter powered devices, need the ability to manually set the host used for connection and prevent it from changing to a less reliable device.
