Fixes #16709

Proposed Changes

• Clamp the configured initial scale to maxScale when maxScale is positive, preventing the KPA scaler from exceeding the configured maximum during initial scaling.
• Apply the same bound when calculating the KPA activation threshold so a revision can become active once the allowed number of pods is ready.
• Add regression tests covering initial-scale bounds, unlimited scaling (maxScale = 0), min/max-scale interactions, unreachable revisions, and activation behavior.

Release Note

Fix KPA initial scaling and activation thresholds to respect maxScale.

Hi @jahnavigajjala-3. Thanks for your PR.

I'm waiting for a knative member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work.

Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.
