* fix(frigate): check OpenVino model files exist before configuring detector

When the OpenVino model build fails (e.g. TensorFlow import error),
the model files are not created but the config still references them
if the CPU supports avx/sse4_2, causing Frigate to crash on start
with FileNotFoundError.

Now also checks that ssdlite_mobilenet_v2.xml and coco_91cl_bkgr.txt
actually exist before configuring the OpenVino detector, falling back
to CPU model otherwise.

Fixes #12808

* fix(frigate): use curl_with_retry for all downloads

Replace all wget and bare curl calls with curl_with_retry from
tools.func for robust downloads with retry logic, exponential
backoff, and DNS pre-checks. This prevents install failures from
transient network issues during model and dependency downloads.
