[Feature] Allow an anonymous user to switch Web interface language

The feature

Some users work in international environments and want to share photos with friends who speak different languages. Would be very nice to have a drop-down list on the web interface to switch to a non-default language.

This deserves a configuration entry that will tell what secondary languages other than default should be allowed. Or maybe allowing to choose any of the 20+ languages is a better idea.

This seems to be the way Immich apps work already — the language is chosen by each user, independent of the server setting. Supporting the same on Web can only make this behavior more uniform.
