fix: P2P Stream timeout for battery cameras relying on STREAM_TIMEOUT_SECONDS

[abhiravk]

Description

Currently, battery-powered doorbells inherently take 3-10 seconds to wake up from deep sleep and negotiate a connection. While a global STREAM_TIMEOUT_SECONDS of 15s is defined in const.py, both camera.py and p2p_streamer.py use arbitrarily hardcoded timeouts (5s and 1s respectively). This causes streams to drop with LivestreamNotRunningError on battery cameras.

This PR replaces the hardcoded asyncio.wait_for(..., 5) with the existing STREAM_TIMEOUT_SECONDS, and calculates the streamer retry limit dynamically based on this config.

Thanks for the PR. Can you post your test results too?

[fuatakgun]

No no, it was already merged. I was just curious, thanks again

[abhiravk]

Thanks for merging.

In go2rtc v1.9.0+, I needed this fix also to make my Eufy camera work.
Without this, go2rtc 1.9.0+ versions throw a 400 Bad Request streams: source not supported error, blocking the dynamically created byte ingest flow completely because it violently rejects unknown schemas).
