Translations update from Hosted Weblate

Snowflake proxy uses defaults in IPtProxy, displays cute toast when user connects. activity text for snowflake proxy isn't in ALL CAPS anymore

Snowflake animations had a bug; they'd appear if tor connects and the pref is set to true even if proxy wasn't enabled (because bridges were...)

- External apps can request orbot to spin up a v3 service
- When cancelled, apps are informed
- When service is created, apps get the .onion url

Also introdued a change where onion service domains are updated when a
fresh connection tor tor is achieved, so users don't have to restart app

Fixes #549 snowflake preferences are greyed out when bridges are in use
