* perf: Lazy import mailparser, @fast-csv, and franc deps
Moves heavy dependencies off the startup path into the narrow async code
paths that actually use them, mirroring the mammoth lazy-import change:
- mailparser: only needed for Confluence Word imports (confluenceToHtml)
- @fast-csv/parse: only needed for CSV imports (csvToMarkdown)
- franc / iso-639-3: only needed by the DocumentUpdateText worker task

* perf: Lazy import jsdom dep
jsdom is one of the heaviest server dependencies but is only needed for
HTML export (ProsemirrorHelper.toHTML) and HTML import
(DocumentConverter.htmlToProsemirror). Move it to a lazy `await import`
inside those methods so its dependency tree stays off the startup path.
Both methods become async; all callers were already in async contexts.
The type-only usage in patchGlobalEnv is now an `import type`.
