feat: Enhance file tag update functionality with automatic format conversion (#84)

- Updated `update_file_tags` to support both simplified and full tag formats.
- Introduced `TagFormatConverter` to handle conversion from simplified external tags to internal storage format.
- Added logic to fetch and utilize the appropriate annotation template for conversion.
- Improved error handling for missing templates and unknown controls during tag updates.
- Created example script demonstrating the usage of the new tag format conversion feature.
- Added unit tests for `TagFormatConverter` to ensure correct functionality and edge case handling.
