fix(emails): Update oauth_client_info service/name check

Because:
* In the verifyLoginCode email, Smart Window and VPN say '...  Mozilla?' (the default) in the subject line/body copy, and we want to be consistent with Sync and Relay and focus on '... Firefox?' wording

This commit:
* Changes the hardcoded check against sync/relay to include the OAuthNativeServices enum to return 'Firefox' as the name

closes FXA-13080
