This PR tightens the Quartz job whitelist validation.
The previous implementation relied on prefix-based checks, which could be bypassed using crafted class or bean names. This change validates the resolved bean’s actual package name and explicitly blocks known disallowed prefixes.
There is no functional impact for valid jobs. The change only improves safety and reduces the risk of misuse.
