fix(ui): permissions on intro & updated settings with anon id

[shanimal08]

Description

• add created_at field to app_config to check if it's the first ever run of the app or not (to hide permissions toggle on the Intro screens on subsequent runs)
• added Application Information settings section in General Settings to display the anon_id which can be copied
• tightened up General Settings styling a little

Motivation and Context

resolves:

• Improve your Experience toggle is always displayed #1123
• Add app anon id under advanced settings #1114

What process can a PR reviewer use to test or verify this change?

re. #1123:

• reset everything/remove app_config and start app - should show permissions toggle on the intro screens
• on any runs after that (not after reset) it shouldn't show on intro screens

re. #1114:

• your app anon_id should be viewable and copy-able(?) from general settings

disabled string check because anon_id is a field name we don't translate, but LMK if that should also be translated

Anon id looks good. Copys fine.

Telemetry toggle stays on the splashscreen on every start despite the new app config option for creation date. Tested with existing wallet, and fresh install.
