Health probe fails when PHOTOPRISM_SITE_URL contains path prefix

[KuuDS]

Description

When PHOTOPRISM_SITE_URL is configured with a path prefix (e.g. "http://192.168.1.100：20800/photoprism"), the Kubernetes health probes fail because they are hardcoded to check the root path "/". The probes attempt to access "http://192.168.1.100:20800/" instead of "http://192.168.1.100:20800/photoprism", resulting in 404 errors and failed liveness checks.

Steps to Reproduce

1. Set PHOTOPRISM_SITE_URL to "http://192.168.1.100:20800/photoprism"
2. Observe that health probes fail with 404 errors

Expected Behavior

Health probes should respect the path prefix defined in PHOTOPRISM_SITE_URL and check the correct endpoint.

Current Behavior

Health probes only check the root path "/", ignoring the configured path prefix, which causes 404 errors and failed health checks.
