Fix playing TTS and local media source over DLNA

[kepler]

Proposed change

If I try TTS or playing a local media audio file on a DLNA compatible speaker, it doesn't work and shows an error in the log:

[homeassistant.components.dlna_dmr] Error during call async_play_media: UpnpActionResponseError('Error during async_call(), status: 500, upnp error: 716 (Resource not found)')

Right before the Resource not found error above, the HA logs show that there's a HEAD request coming in from the speaker and that fails with an HTTP 500 error. I also saw somewhere someone hinting that DLNA renderers might send a HEAD request before sending the GET one.

This PR adds support for HEAD requests for local_source media and TTS (also allowing signed requests for HEAD), which fixes this problem and likely related issues mentioned below.

Type of change

• Dependency upgrade
• Bugfix (non-breaking change which fixes an issue)
• New integration (thank you!)
• New feature (which adds functionality to an existing integration)
• Deprecation (breaking change to happen in the future)
• Breaking change (fix/feature causing existing functionality to break)
• Code quality improvements to existing code or addition of tests

Additional information

There are several reports around the net about this or related DLNA problems, dating back to 2022:

• Unable to play any media on DLNA media renderer #81162
• Media Player Cast does not work with DLNA devices #111078
• Media Cast / DLNA not working with Samsung TVs or Smart Monitors
• DLNA Digital Media Renderer Not Working

Most replies to such issues end up pointing to configuring media_dirs (Setting up local media sources, Media Source), but nothing works, leading to complains about unclear documentation: home-assistant/home-assistant.io#28940.

Also, the documentation says there might be hiccups with Samsung devices, but that might be exactly because of the missing support for HEAD requests:

Note that some devices, such as Samsung TVs, are rather picky about the source used to play from. The TTS action might not work in combination with these devices.

However, I haven't tried streaming videos yet. I'll check it later and submit a separate PR if necessary, and it seems to also be an issue like #67618.

Just to confirm that this also fixes streaming video to my Samsung TV.
