Construct.
Note: __constructor (no double-underscore in Soroban 22) runs
automatically at deploy. We store the immutable display/metadata
fields here. The minter is set in a follow-up call from the
Factory (or YieldStripping) via [Self::initialize_minter].
fn __constructor(env: soroban_sdk::Env, args: PtInitArgs)Set the minter exactly once. The factory calls this immediately
after deployment with the address of the parent YieldStripping
contract. Subsequent calls revert with AlreadyInitialized.
No require_auth here — calling this address is the bootstrap
privilege. In production deployments the factory wraps the entire
deploy + init pair in one transaction so no other principal can
race the call.
