aider: Ensured all handlers conform to `slog.Handler` interface and removed `NewEvent()` constructor calls.

# Aider chat conversation:

USER: we are creating a custom handler for the log/slog package, which configures its own list of sub-handlers and dispatches events to all of those.  all of the subhandlers should conform to the log/slog slog.Handler interface, as should our custom handler.  The NewEvent() constructor does not exist and the call to it should not exist, we are using the events dispatched to us from the log/slog package.

ASSISTANT: To ensure that all sub-handlers conform to the `slog.Handler` interface and to remove the `NewEvent()` constructor, we need to make the following changes:

1. Update `CustomHandler` to implement the `slog.Handler` interface.
2. Remove the `NewEvent()` constructor calls from the sub-handlers.
3. Ensure that the `Log` method in each handler conforms to the `slog.Handler` interface.

Here are the necessary changes:
