Update StatusRoundButton colours to support a "tertiary" style (background and icon color overlay), as well as tertiary hover colour.
Fix the modal header close button so that it more closely matches the design.
Replace the buttons in the onboarding modals with StatusRoundButtons were possible.
Closes: #586
Previously, loading sticker packs and stickers would show a lot of blank and non-interactive content.
Now, stickers and sticker packs have grey circles to indicate loading. Additionally, the sticker market button (+) shows a loading indicator until the sticker packs are loaded.
This component is similar to a StatusRoundButton that holds an icon.
However, the StatusRoundButton has a fixed number of variations based on the
designs. Sometimes we need clickable icons that have a different look and feel
E.g. in the chat input component.
This component aims to cover that use case.

This PR is based off of #1036, which supports system colors at app startup, meaning the onboarding screens may be in dark mode, if the user has their system set to dark mode. This PR fixes the onboarding screens so they support dark mode.
It also:
1. Adds radio buttons to the `AccountList` component, as per the design
2. Adds `qsTr` where missing on the onboarding screens
3. Fixes some minor design issues
4. Updates the modals titles to match the design
5. Uses reusable Status components where possible. `EnterSeedPhraseModal` and `GenKeyModal` could have used the `StatusRoundButton` component, but there were some limitations that preventing this from being possible.
Supports system dark mode. Changes the user appearance setting to a 3-way setting of System, Light, Dark.
New accounts will have their appearance setting set to "System", which uses the system setting to determine if dark mode should be applied.
Breaking change: Users who had their settings on Light Theme, will now get the system theme (light or dark). Users who had their theme set to Dark, will now get the Light theme.
At startup, the onboarding screens will have the system-level setting of dark mode applied or not. Once, logged in, the user settings will be applied.
## Note
An appearance setting of "System" is not dynamic to the system-level setting. This means that if a user has "System" set for their appearance (and ie, the user has light mode set), and then user then changes their system setting from light to dark, the app will not respond until it is restarted. This is due to a limitation of Qt not having a reliable way to propagate these changes to QML.

Adds a loading state to stickers, so that a loading indicator appears while the sticker is being downloaded from IPFS.
In the case of a network failure or timetout, a reload button is shown instead. Once network is restored and the reload button is clicked, the image is reloaded from the network, going through the same lifecycle of showing the loading state first.
