✨ (whatsapp) Add custom session expiration (#842)

<!-- This is an auto-generated comment: release notes by coderabbit.ai
-->
### Summary by CodeRabbit

- New Feature: Introduced session expiry timeout for WhatsApp
integration, allowing users to set the duration after which a session
expires.
- New Feature: Added an option to enable/disable the start bot condition
in WhatsApp integration settings.
- Refactor: Enhanced error handling by throwing specific errors when
necessary conditions are not met.
- Refactor: Improved UI components like `NumberInput` and
`SwitchWithLabel` for better usability.
- Bug Fix: Fixed issues related to session resumption and message
sending in expired sessions. Now, if a session is expired, a new one
will be started instead of attempting to resume the old one.
- Chore: Updated various schemas to reflect changes in session
management and WhatsApp settings.
