feat: persist access token and metadata access token in seedless controller (#6060)

## Explanation

- This update introduces two new tokens, accessToken and
metadataAccessToken, to the SeedlessOnboardingController.

- These tokens are essential for pairing with the profile sync auth
service and accessing the metadata service before the vault is created
or unlocked.

- The changes include updates to the controller state, methods for
handling these tokens, and corresponding tests to ensure proper
functionality and error handling when tokens are missing.

- Additionally, the vault data structure has been modified to include
the new accessToken. Tests have been added to verify the correct
behavior of the controller with respect to these tokens.

- Removed unused nodeAuthTokens from vault.

- Toprf sdk updated to use metadataAccessToken
