Feat/lookup table

[Oghma]

Summary

Add to the core contract the methods for recording Soroban addresses under a canonical hash and resolving those hashes back to addresses.

Changes

• Add hash_address helper using the address StrKey string bytes as the hash input.
• Add record_address and get_address_from_hash to the Wormhole Core interface.
• Store address lookups under StorageKey::AddressTable.
• Extend storage TTL on address lookup writes and reads.
• Add AddressNotFound for missing lookup entries.
• Add unit tests for address lookup round trips and missing hash behavior.

Breaking changes

None.

Notes

The address hash intentionally uses the Soroban address StrKey string bytes, not raw account or contract bytes.
