WIP: ble: add next gen profile

[kienvo]

This profile allows communicating in both ways which resolves #33.

I am working on adding configurations using this profile. And it may resolve #64, #52, #60, #41, #34, #32

Summary by Sourcery

Add next generation Bluetooth profile to enable bidirectional communication and configuration.

New Features:

• Introduce a new Bluetooth profile for bidirectional communication, addressing issue Define new BLE characteristics/services for new features data exchanges #33.

Tests:

• Remove some test code related to battery status and charging.

Reviewer's Guide by Sourcery

This pull request implements a new Bluetooth Low Energy (BLE) profile to enable bidirectional communication, addressing issue #34. It introduces a new service and characteristics for data exchange and adds support for battery level and device information services. The update also includes changes to the device's power management, animation sequences, and configuration handling.
