We use `export default` begrudgingly here. Ideally we'd use just `export`, though this entire SDK expects things to be exported as a default. Instead of breaking everything, we'll sacrifice our export pattern for a smaller diff - a later commit can always do the default export -> regular export conversion.
This moves the details of dialogs that may be needed when accessing secret
storage to centralised helper. In addition, this clears the secret storage key
cache so that keys are only live for a single operation.
This adds dialogs for creating and accessing secret storage via a passphrase or
recovery key. These flows are adapted from the ones used for key backup.
This is not part of any designs, so it may be short-lived, but it's quite handy
for diagnosing issues with cross-signing at least while the feature is in
development.

This also fixes a bug where the the theme logic can incorrectly get stuck in the light theme - the ThemeController was overriding *all* values, not just supposed themes. Null values aren't overridden so that the various theme logic bits don't assume the user has chosen the light theme explicitly.
We already intercepted most of the cases where no integration manager was present, though there was a bug in many components where openAll() would be called regardless of an integration manager being available.
The integration manager being disabled by the user is handled in the IntegrationManager classes rather than on click because we have quite a few calls to these functions. The StickerPicker is an exception because it does slightly different behaviour.
This also removes the old "no integration manager configured" state from the IntegrationManager component as it is now replaced by a dialog.
We are not supporting this due to the complexity involved in switching integration managers. We still support custom ones under the hood, just not to the common user. A later sprint on integrations will consider re-adding the option alongside fixing the various bugs out there.
