Add retry controls for recoverable failures

[Naomi-Gift]

Problem

Some failures, such as network request errors or temporary RPC issues, require users to manually refresh or restart a flow.

Suggested fix

Add retry buttons for account loading, verification status checks, project loads, and transaction polling failures.

Acceptance criteria

• Recoverable error states include retry actions.
• Retry actions reset loading/error state properly.
• Repeated failures do not create duplicate submissions.
