feat!: add file date metadata to db

* fix: correctly display duration statistic in preview panel

* style: format file_attributes.py with ruff

* refactor: consolidate preview thumb current file state

* refactor: remove another redundant current file state

* refactor: move generic format_duration function to string formatting util file

* refactor: tighten signal's declared types
