Add new ECS log format

[hilarex]

Summary

This PR introduces a new ECS-compatible logging format for Trapster, with a modular logger refactor that enables flexible format/output combinations while preserving existing logger compatibility.

• Split monolithic logger implementation into trapster/logger/ with one module per logger component (base, json, file, api, redis, ecs, factory, __init__).
• Added a new composable logging path:
  • formats: default, ecs
  • outputs: terminal, file, api, redis
• Introduced OutputLogger + formatter layer so config can express combinations like:
  • default JSON -> API
  • ECS -> API
  • default JSON -> terminal
• Kept retrocompatibility with existing name-based logger configs (JsonLogger, FileLogger, ApiLogger, RedisLogger, EcsLogger).
• Expanded and normalized ECS output semantics:
