Resolved merge conflicts by aligning e2e test helpers with the updated upstream signatures that now require `context.Context`.

Resolved merge conflicts by aligning e2e test helpers with the updated upstream signatures that now require context.Context.

Specifically:

• Added context.TODO() to e2e helper calls (WaitForLoadBalancer, Run, UpdateService, TestReachableHTTP, WaitForLoadBalancerDestroy) to match current function signatures.
• Removed duplicate variable declaration for loadBalancerCreateTimeout.
• Preserved existing test logic and behavior; changes are limited to signature compatibility and conflict cleanup only.

No functional changes to test semantics—this is a mechanical resolution to keep the cherry-picked commits compatible with release-1.31.

Backport upstream commits #1153, #1161, #1215, #1217, #1214 to release-1.31.

Conflict resolution details:

• Updated calls to match upstream API signatures that now require context.Context, applying context.TODO() where appropriate.
• Removed duplicate variable declaration for loadBalancerCreateTimeout.
• No functional changes were introduced — existing test logic and behavior are preserved.
• All tests pass after resolving conflicts.

These changes ensure the cherry-picked fixes cleanly apply to the release-1.31 branch and maintain compatibility with upstream helper signatures.
