tech-debt: react-hooks/exhaustive-deps suppressed across several hooks/components

[Ejirowebfi]

Summary

The react-hooks/exhaustive-deps ESLint rule is suppressed in multiple hooks/components instead of fixing the dependency arrays, which masks stale-closure bugs.

Evidence

• frontend/src/hooks/useTransactionHistory.ts:79,86
• frontend/src/components/MintForm.tsx:110
• frontend/src/components/UI/OnboardingModal.tsx:62
• frontend/src/components/TokenHistory.tsx:56

Impact

exhaustive-deps violations are a common source of "data doesn't refresh" / stale-value bugs. The TransactionHistory suppressions co-locate with its known pagination/caching bugs.

Suggested fix

Audit each effect: stabilize callbacks with useCallback, include the real dependencies, and remove the disables. Where an effect intentionally runs once, encode that explicitly rather than silencing the linter.

I've reviewed the issue and believe I can help resolve it. My plan would be to investigate the underlying cause, implement a maintainable fix, and verify the changes through comprehensive testing before submitting a pull request.

Feel free to assign it to me if it's still available.
