Retrieves the block number and timestamp for a specific date/time or the latest block.
Use when you need a block height for a specific point in time (e.g., "block at 2024-01-01")
or the current chain tip. If datetime is provided, finds the block immediately
preceding that time. If omitted, returns the latest indexed block.
