Fix untranslated UI keys (raw "snake_case" labels) + anonymous edit links

The frontend bundles only the locale keys listed in
frontend/extracted-translations.json (a custom webpack translations-loader
filters en.json to that set, normally regenerated by i18next-scanner). Every
key added by hand to en.json without also adding it here renders as its raw
key — which is why "blank_quarto_project", "share_compiled_presentation", etc.
showed up literally in the New-project menu and Share dialog.

Add all introduced keys to extracted-translations.json: blank_/example_
{quarto,latex,typst}_project, share_compiled_presentation(_info),
presentation_link_{members,private,public}, reset_link.

Also enable anonymous read-AND-write share links (edit without an account) via
OVERLEAF_ALLOW_ANONYMOUS_READ_AND_WRITE_SHARING; read-only links already worked
through OVERLEAF_ALLOW_PUBLIC_ACCESS.
