fix: prevent SERVICE_FQDN/SERVICE_URL path duplication on FQDN updates

Add endsWith() checks before appending template paths in serviceParser() to
prevent duplicate paths when parse() is called after FQDN updates. This fixes
the bug where services like Appwrite realtime would get `/v1/realtime/v1/realtime`.

Fixes #7363
