Fix flaky router private key PEM test

[googs1025]

Fixes a flaky router test seen in coverage:
https://github.com/volcano-sh/agentcube/actions/runs/26986069745/job/79635856049

The parsed RSA key is equivalent, but CRT internals can differ by leading zero bytes. Use rsa.PrivateKey.Equal for the assertion.

Pull request overview

Note

Copilot was unable to run its full agentic suite in this review.

Updates JWT private key PEM unit test to compare RSA private keys by value rather than by pointer/reference, aligning the assertion with how parsed keys are represented.

Changes:

• Replace assert.Equal with (*rsa.PrivateKey).Equal-based assertion for private key comparison.
