Ambilight+Hue on Philips 58PUS7805 TV does not detect Bifrost

Hi there 👋,

First of all, thanks for creating and maintaining Bifrost.

I’ve been trying to get my Philips 58PUS7805 TV to work with Ambilight+Hue using Bifrost, but unfortunately, the TV doesn’t seem to detect the bridge.

Here’s what I found while investigating:
- The TV does not send any SSDP/M-SEARCH requests on the local network, so local discovery doesn’t work.
- It only reaches out to `discovery.meethue.com` via HTTPS.
- I even set up a local HTTPS proxy for `discovery.meethue.com` that correctly exposes the Bifrost bridge information (ID, internal IP, and port) but the TV still ignores it.

### Technical Details

- **TV model:** Philips 58PUS7805
- **TV firmware version:** mt5887:TPM206E_201.003.248.001
- **Bifrost version:** dev-2025-05-20 (bifrost-hassio)
- **Tested with:** Hue app, Hue Essentials → works perfectly for controlling lights
- **Attempts made:**
- Local SSDP discovery → TV does not send M-SEARCH
- HTTPS proxy simulating `discovery.meethue.com` → correctly returns Bifrost bridge info including ID, internal IP, and port, but TV still ignores it

### Context and question

My goal is to completely remove the Hue Bridge from my setup, as this is the only functionality that currently forces me to maintain a second Zigbee network for a few lamps in my living room.

Does anyone have an idea why the TV doesn’t detect Bifrost, even though the bridge info is correctly exposed?
