fix(cct-sdk): Refactor solana token-admin-registry ops

[mervin-link]

What

• Refactor Solana TokenAdminRegistry lookup-table operations to support canonical poolType or custom poolProgramAddress
• Centralize pool-program reference types and resolution
• Improve lookup-table and set-pool test organization and validation coverage (generate, validation, execute)
• Refresh the root lockfile for npm ci compatibility

Why

• Make Solana CCT pool operations easier to use with canonical pool types while preserving custom-program support
• Ensure to keep test coverage aligned with the operation lifecycle

Note

• I'll follow up to refactor the remaining test files.
• Removed current cct exports in ccip-sdk/package.json because it's causing build errors in CI (Validate package exports) where it's exported but it does not exist. Then I added pack:cct script to bundle ccip-sdk that will include cct features.
• Run npm run pack:cct -w ccip-sdk to bundle the package.
