fix: prevent option ID collisions in CreateSurvey component

[Copilot]

The addOption function used Math.max to generate IDs, causing collisions when options were removed then added:

// Before: IDs could collide
id: Math.max(...prev.survey.options.map((o) => o.id), 0) + 1
// Add option #2 → Remove #2 → Add option → ID 2 reused ❌

// After: monotonic counter prevents collisions
const nextOptionIdRef = useRef(2);
// Add option #2 → Remove #2 → Add option → ID 3 assigned ✓

Changes:

• Replace Math.max calculation with useRef counter that increments independently of removals
• Reset counter when form is reset to maintain consistent state
• Add test verifying unique IDs after remove/add sequences

@copilot rebase these changes onto the target branch to get the latest changes from the target

I'm unable to perform a rebase operation because:

1. Force push is not available in this environment (required for rebase)
2. The target branch for PR feat: add tests for CreateSurvey, GetSurvey, and MySurveys components #2597 is not available in the repository
3. This is a shallow clone with limited history

Could you either:

• Perform the rebase locally, or
• Let me know if there are specific changes from the target branch that need to be incorporated, and I can apply them manually?
