feat: force sync route after sandbox resume

[PersistentJZH]

Ⅰ. Describe what this PR does

Add force route synchronization in sandbox-manager after resuming sandbox to ensure all peer instances are aware of route changes (especially PodIP) without waiting for informer watch events.

Changes:

• Add PauseSandbox and ResumeSandbox methods to SandboxManager
• Replace direct sbx.Pause/Resume calls in e2b controller with SandboxManager methods
• Add InplaceRefresh before route sync to ensure latest PodIP and State

@PersistentJZH
I think it's not necessary to make it so complicated. Refer to the ClaimSandbox method of SandboxManager (api.go), add a set of Pause/Resume methods, roughly the logic:

func (m *SandboxManager) PauseSandbox(ctx context.Context, sbx infra.Sandbox) error {
    sbx.Pause(ctx)
    m.proxy.SyncRouteWithPeers(sbx.GetRoute())
}

And just replace the direct calls to sbx.Pause/Resume in the e2b controller.

thanks @AiRanthem, pls help to review again

[AiRanthem]

The synchronous routing code after pause and resume looks somewhat repetitive. Could we consider extracting it into a common function?
