refactor: restructure plugins per MTSS standard, consolidate assets to res/

Per docs/plugin-audit-report.md (plugins normalized to
Trigger(handlers) → Service(services) → Model(repository/models) + utils):

- Split monolithic __init__.py into handlers/services/utils across
  dailywife, deer_pipe, dice, galgame_card, helldivers_tools,
  huoziyinshua, learning_chat, makeaquote, mc_server_status,
  ncm_saying, picfinder_take, picstatus, random_jm_code, regif,
  steam_info, video_analysis, group_tools
- Move static assets under res/: deer_pipe font/img, makeaquote font,
  helldivers img/templates, huoziyinshua HuoZiYinShua
- Add config.py + register_config_items to ncm_saying, random_jm_code,
  group_tools; learning_chat unified config bridge
- Remove deprecated: voice_trans plugin, bf_bot/test.py, dead code in
  dailywife/deer_pipe, empty dirs, debug scripts under helldivers temp
- Disable brash_general_supercredits_tools (stub comment only)
- bot.py: optional stdout/stderr redirect to log file for Web log viewer,
  force ANSI colorize on non-TTY sinks
- Move runtime data (jm_code.json) out of plugin dir into hexi/data
- Docs: plugin-audit-report.md; README reflects removed plugins
