feat: Enhance Solana tools with action-based architecture

- Introduced action system for Solana tools, allowing for better modularity and maintainability.
- Updated SolanaBalanceTool, SolanaTransferTool, SolanaDeployTokenTool, SolanaDeployCollectionTool, SolanaMintNFTTool, SolanaTradeTool, and SolanaRequestFundsTool to utilize action handlers.
- Added new action exports in index.ts for better organization and accessibility.
