Fix @typescript-eslint/no-base-to-string instances

[iamacook]

Summary

When updating to ESLint 9, some rules had to be ignored as their recommendations changed. Of which, was the @typescript-eslint/no-base-to-string rule.

This removes instances of where values that can't be stringified are being stringified.

Changes

• Enable @typescript-eslint/no-base-to-string ESLint rule
• Stringify addresses, not objects of signers in:
  • routes/email/guards/email-edit.guard.spec.ts
  • routes/email/guards/email-retrieval.guard.spec.ts
