[Feature Request] Automatically send-to-kindle when new book added

[xiNeRoar]

Is your feature request related to a problem? Please describe.
I find it frustrating that I have to manually send newly added books to my Kindle every time I add them to the software. This process can be tedious, especially when dealing with multiple books. Automating this step would save time and improve the overall user experience.

Describe the solution you'd like
I would like the software to have an option to automatically send newly added books to Kindle via the Send-to-Kindle service. Whenever a new book is added, it should be automatically sent to a predefined Kindle email address without requiring manual intervention. A setting should allow users to enable or disable this feature and configure their Kindle email address.

Describe alternatives you've considered

Manually sending books to Kindle each time a new book is added. This is inefficient and adds unnecessary steps.
Using third-party scripts or external automation tools, but these require additional setup and may not integrate smoothly with the software.
Setting up an external email automation process, which can be complex and unreliable compared to a built-in solution.
Additional context

It would be helpful to have options to choose the preferred format (e.g., MOBI, EPUB, PDF) before sending.
An option to delay sending (e.g., send in batches once a day instead of instantly) could be useful.
A log or history of sent books would be beneficial for tracking.
The feature should respect Kindle's file size and format limitations to avoid errors.
