[Feature]: Remove stale OTP resend token storage

[Bccorb]

Problem statement

The phone verification flow stores data.token in localStorage after resending an OTP, but this repo does not appear to read that value anywhere anymore.

This looks like leftover logic from an older flow and makes the current behavior harder to reason about.

In src/views/PhoneRegistration.tsx:

• resend phone OTP
• parse response JSON
• if data.token exists, write it to localStorage

There does not appear to be any active consumer of that stored token in this package.

Proposed solution

Acceptance criteria

• No stale or unexplained localStorage writes remain in the OTP flow
• Tests reflect the intended behavior
• If token storage remains, it has a documented purpose and an active consumer

Alternatives considered
