feat: Support importing .docx or .html files as new documents (#1551)

* Support importing .docx as new documents

* Add html file support, build types and interface for easily adding file types to importer

* fix: Upload embedded images in docx to storage

* refactor: Bulk of logic to command

* refactor: Do all importing on server, so we're not splitting logic for import into two places

* test: Add documentImporter tests
