Summary
Implements dynamic account sizing for DirectRecipient following the escrow program pattern. Accounts now vary from 116-140 bytes based on VestingSchedule variant instead of fixed 140-byte padding. Adds VestingSchedule::byte_len() method and updates account creation to calculate actual size needed. All integration tests updated and passing.
