Implement Address wrapper around strkey for safe handling of Contract IDs

[Emrys02]

Raw contract strings (C...) and account IDs (G...) are easy to mishandle. A strong Address wrapper prevents invalid identifiers from entering the application's core logic.

Implementation Guidelines

Key Files: crates/core/src/types/ (create or update relevant type files).

• Define an Address struct wrapping stellar-strkey::Contract and stellar-strkey::PublicKey.

Expectations

What done looks like: An Address struct that strictly represents a validated Stellar or Soroban address.
