feat: add automatic CTWA (Click-to-WhatsApp) ads message recovery
Messages from Facebook/Instagram ads (Click-to-WhatsApp) don't arrive on linked devices because Meta's ads endpoint doesn't encrypt for multi-device. They arrive as "Message absent from node" placeholders. This change automatically requests the message from the primary phone via PDO (Peer Data Operation) when a CTWA placeholder is detected. Changes: - Add enableCTWARecovery config option (default: true) - Trigger requestPlaceholderResend() for "Message absent from node" errors - Add comprehensive unit tests for CTWA recovery functionality Resolves: https://github.com/WhiskeySockets/Baileys/issues/1723 Resolves: https://github.com/WhiskeySockets/Baileys/issues/1034
