Miscellaneous fixes (0.18 beta) (#23854)

* fix watchdog process restarts reverting to the boot config

/api/config/set parses a new FrigateConfig and swaps the API and dispatcher onto it, but FrigateApp.config was never rebound, so the watchdog factories rebuilt a crashed process from the config as of startup. Fix is to read through a ConfigHolder that the swap updates.

* fix birdseye camera overrides being clobbered by a global mode change

A global birdseye save published only the global object, leaving the output process to infer which cameras were inheriting by comparing against the previous global mode. That cannot tell an inherited value from an explicit one that happens to match, so it overwrote the override until a restart. Publish the per-camera values the config parse already resolved instead.

* Reject non-finite numbers in GenAI review descriptions

A model returning NaN for confidence or potential_threat_level slipped through the model_construct fallback, which skips validation, and was written into the review segment's JSON data. NaN is not valid JSON, so every subsequent /review request failed with "Out of range float values are not JSON compliant", blanking the review page for any time range containing the poisoned row.

* restore fused DetectionOutput in the OpenVINO SSD model conversion

* fix rgb swap issue for face dataset testing script
