[_]: refactor/webhook cleanup

[xabg2]

This PR centralizes the logging approach across the webhooks module by replacing the pattern of passing the Fastify logger as a dependency through multiple function calls and class constructors. Instead, we now use the centralized Logger object directly where logging is needed. This eliminates unnecessary parameter drilling and makes the code cleaner and easier to maintain.

Additionally, this refactor removes other unused dependencies that were being passed around without purpose, such as the config object in several webhook handlers and the direct Stripe instance injection in the app setup (now using the existing stripePaymentsAdapter singleton instead). The webhook entry functions have also been renamed to be more descriptive (providerWebhooksEvents, cryptoProviderWebhooks) and their signatures updated to use a configuration object instead of positional parameters for better readability.
