Fixing evm to svm account storage issue by adjusting ccip message storage flow.

[Copilot]

Pull request overview

This PR adjusts the Solana spoke’s CCIP settlement flow to avoid immediate intent-status PDA creation during ccip_receive by persisting settlement data in SpokeState and introducing a follow-up instruction to finalize delivery.

Changes:

• Add pending_ccip_settlement to SpokeState and introduce a new settle_ccip_delivery instruction to create the intent_status_pda with Delivered status later.
• Add a v2 spoke-state migration (migrate_spoke_state_v2) to realloc the state PDA for the new field.
• Extend error handling and exports to support the new pending-settlement workflow.
