- Re-use the saved emoji as the default for future callout cards
- Introduced a localstorage util that ignores errors. Ignoring errors avoids issues with browsers that don't support localstorage

- Stored in the payload as an hexadecimal (or variable) value
- chosen with a dropdown through a pre-selected list of colors (or the publication accent color)

- Uses the KoenigSettingsPanel to display a toggle
- The Emoji is set to an empty string when disabled
- And arbitrarily set to 💡 by default when toggled back on
no issue
The logic for "delete if empty" was duplicated in two places:
1. when `createComponentCard` is used to register a card, this option method was used when cleaning up a post when first rendering (cards in empty state can be saved before the editor auto-removes them but we don't want to show them again)
2. inside of card's own delete-if-empty handling on certain actions such as deselection or leaving edit mode
- added an `ifEmpty` property to each card component
- used by the editor's first-render cleanup routing if the property is present
- can be re-used internally for the card's own deselect/exit-edit-mode behaviour
- updated the cleanup routine in `<KoenigEditor>`
- added a `allComponentCardsRegistered` property that will return `true` when the `.component` property is set on every card (the property is set during card component initialisation so we're at the mercy of Ember's render process so not all card components will be immediately registered)
- swapped `_cleanup` for `_cleanupTask` that will wait for `allComponentCardsRegistered` to be `true` before performing cleanup, ensuring that we always have access to the card component's `isEmpty` property even when Ember renders cards across multiple render batches
- checks for `isEmpty` being a boolean and will delete the card if it's value is `true`
- updated all cards that had delete-if-empty behaviour
- added `isEmpty` properties
- removed duplicated logic in the `createComponentCard` calls
