[Feature Request] Support autoplay when Bluetooth headphones are connected with IFTTT

### What problem does this address?

Currently, the app supports auto-play episodes when Bluetooth headphones are connected with Tasker. We have a request in 6341982-zd-woothemes to recreate the same effect with IFTTT.

### What is your proposed solution?

Support IFTTT integration with Pocket Casts to allow auto-play episodes when Bluetooth headphones are connected to the device.

### Did you search for existing feature suggestions?

- [X] I have searched for existing feature suggestions.

Start by locating the existing Tasker integration that auto-plays episodes when Bluetooth headphones connect, then investigate how an IFTTT integration could provide the same trigger in the Android app. Confirm the expected Pocket Casts and IFTTT interaction, and consider how the behavior can be tested; done means Bluetooth headphone connections through IFTTT reliably trigger episode autoplay.
