refactor: remove bs58 dependency and use solana_sdk program ID constants

- Remove standalone bs58 dependency and rely on the solana_sdk re-export
- Switch system and token program IDs to the idiomatic spl_token / solana_sdk constants
- Use pubkey! and LazyLock for cleaner program ID initialization
- Alias solana_entry::Entry as SolanaEntry to avoid a naming conflict with gRPC types
- Remove unused FromStr imports and some redundant logic
