* feat: Recreate mesh service after panic clear

This commit refactors the panic clear process to ensure a new mesh identity is immediately created and applied.

Previously, the `ChatViewModel` would clear sensitive data, but the recreation of the `BluetoothMeshService` was handled externally. This could lead to a delay or failure in adopting the new identity.

Key changes:
- Introduces `MeshServiceHolder` to manage the lifecycle of the `BluetoothMeshService` instance.
- Adds `recreateMeshServiceAfterPanic()` to `ChatViewModel`, which now explicitly clears the old service instance and creates a new one with a regenerated identity.
- The `meshService` property in `ChatViewModel` is now a `var` to allow it to be replaced with the fresh instance post-panic.
- The new service is started, and a broadcast announcement is sent immediately, ensuring the new peer ID is used on the network.

* fix: Ensure mesh service is properly managed in foreground service

* refactor: Decouple handlers from direct service reference

This commit updates the `VerificationHandler` and `MediaSendingManager` to receive the `meshService` via a lambda function (`getMeshService`) instead of a direct reference.

This change decouples the handlers from the service instance, preventing them from holding a stale reference if the service reconnects or changes. By invoking the lambda to get the current service instance when needed, it ensures they always interact with the active `meshService`.

* fix: restart bluetooth
