fix(transhandler): suppress noisy error notification for TV special and extra sample files without episode numbers

BD-BOX releases for Anime and TV shows frequently contain extra non-episode video files (such as NCOP, NCED, Menu, PV, CM, SP, Event, Logo, etc.). When transferring these single files, the lack of an episode number previously logged a warning and triggered a noisy '整理失败：未识别到文件集数' notification to users.

This change identifies known special/extra file patterns when begin_episode is None, logs them at INFO level, and suppresses the error notification while returning success to avoid false-positive failure alerts.
