Update frigate to version v0.15.0

[nmfretz]

🤖 This is an automated pull request to update frigate to version v0.15.0. This PR must be reviewed and tested before merging.

Auto-generated update considerations:

• Database backup recommended before upgrade - copy frigate.db file when Frigate is stopped
• SHM system rewritten - requires correct shm_size setting, check logs for warnings about required size
• Recording configuration structure changed - verify retention settings for alerts and detections after upgrade
• FFmpeg updated to version 7 - Intel users may need to change hwaccel presets (vaapi to intel-qsv-h264/h265)
• FFmpeg path changes - go2rtc 'exec' streams need full path '/usr/lib/ffmpeg/7.0/bin/ffmpeg'
• go2rtc config needs 'bin: ffmpeg' removed if present
• Model configuration simplified - 'model' config under 'detector' changed to simple 'model_path' string
• New storage requirements for Semantic Search feature - 16GB RAM and GPU recommended
• Database will store new data if GenAI Search feature is enabled

Linting Results

Severity	File	Description
ℹ️	frigate/docker-compose.yml	External port mapping "8554:8554": Port mappings may be unnecessary for the app to function correctly. Docker's internal DNS resolves container names to IP addresses within the same network. External access to the web interface is handled by the app_proxy container. Port mappings are only needed if external access is required to a port not proxied by the app_proxy, or if an app needs to expose multiple ports for its functionality (e.g., DHCP, DNS, P2P, etc.).

ℹ️	frigate/docker-compose.yml	Potentially using unsafe user in service "web": The default container user "root" can lead to security vulnerabilities. If you are using the root user, please try to specify a different user (e.g. "1000:1000") in the compose file or try to set the UID/PUID and GID/PGID environment variables to 1000.
⚠️	frigate/docker-compose.yml	Invalid restart policy: The restart policy of the container "web" should be set to "on-failure".
