feat: Typst → LaTeX import, and fix export button visibility

Typst → LaTeX import:
- CLSI ConversionManager: add 'typst' to CONVERSION_CONFIGS
  (pandoc input.typ --from typst --to latex --standalone → zip archive)
- Web controller: allow 'typst' as a valid importDocument conversion type
- Frontend modal: add .typ file config to ImportDocumentModal
- New project button modal: add 'import_typst' variant + switch case
- New project button: show "Import Typst file" when enablePandocConversions
  is true (no split test gate — Verso has no SaaS split test infra)
- Locales: add choose_typst_file and import_typst_file keys (18 locales)

Export button fix:
- Remove featureFlag="export-typst" from ExportProjectWithConversionButton
  so the button shows whenever enablePandocConversions is true, without
  needing an unconfigured split test to return 'enabled'
