fix: complete APKG format with all required Anki fields

Based on Anki-Android database documentation:
- Added 'autoplay' field to deck configuration
- Added 'dyn' field to deck configuration
- Added 'separate' field to new card settings
- Added 'minSpace' field to review settings
- Added 'replayq' field for replay queue
- Added 'tags' array to note type
- Added LaTeX pre/post fields for math support
- Added 'media' arrays to all field definitions
- Added missing collection config fields (schedVer, collapseTime, etc.)
- Fixed 'ivlFct' field in review settings
- Added 'bury' flags to new and review sections

This should resolve all JSON parsing errors when importing APKG files into Anki desktop.
