chore: improved logging infra and added 'component', 'containerId' and 'event'

[DeepSpace2]

Summary by CodeRabbit

• Refactor

  • Moved to component-scoped named loggers for clearer log attribution.
  • Added context-based logger propagation for request/container-scoped logging.

• New Features

  • Added a utility to produce consistent short Docker container IDs (12-char truncation).

📝 Walkthrough

Walkthrough

This PR adds component-scoped named loggers and context-based logger propagation, migrates package-level loggers to component names, adds a Docker container ID truncation helper, and refactors processor handlers to receive and use context-propagated loggers.

Changes

Component-scoped logging with context propagation

Layer / File(s)	Summary
Logging API: component-scoped loggers and context helpers pkg/logging/log.go	Core logging package refactored to accept a component name in GetLogger(component string), attach it as a structured component field, and introduce WithLogger(ctx, logger) and FromContext(ctx) helpers for context-based logger propagation with fallback to global logger.
Package logger migrations to named loggers main.go, pkg/clients/clients.go, pkg/clients/docker/docker.go, pkg/clients/npm/npm.go, pkg/clients/adguardhome/adguardhome.go, pkg/clients/pihole/pihole.go, pkg/config/config.go, e2e_tests/e2e_test.go	Package-level loggers updated to call GetLogger() with explicit component names (e.g., "main", "clients", "docker", "npm", "adguardhome", "pihole", "config", "e2e").
Docker container ID truncation utility pkg/clients/docker/docker.go	Adds GetShortContainerId(containerId string) to Docker client; returns the input unchanged if shorter than 12 characters, otherwise truncates to the first 12 characters.
Processor context-scoped logging and handler refactoring pkg/processor/processor.go	Processor initializes named logger and refactors DNS handler functions (handleAdguardHome, handlePiHole, handleNpm) to accept ctx and derive loggers via FromContext(ctx). processContainer now creates a scoped logger with host/container fields, uses WithLogger to attach it to ctx, updates dry-run logs to include ip, port, and urls, and removes explicit "host"/"container" fields from handler log calls.
