No public token getter in vesting wallet

[ritaifeoluwa]

Description

The vesting wallet does not have a way to query the token address. While get_token exists internally, there is no public getter.

Current behavior

get_token is a private function.

Expected behavior

Add a public getter:

pub fn token(env: Env) -> Result<Address, VestingError> {
    require_initialized(&env)?;
    Ok(get_token(&env))
}

Why this matters

Frontend apps need the token address for display and transaction building.
