Log when we show, and hide, encryption setup toasts

[richvdh]

It's currently hard to debug when someone sees or hides one of these toasts. Lets's add some logging.

Unless anyone has severe objections, I'd like for this to go in the forthcoming release to help us handle the ongoing feedback with these toasts.

The backport to staging failed:

The process '/usr/bin/git' failed with exit code 1

To backport manually, run these commands in your terminal:

# Fetch latest updates from GitHub
git fetch
# Create a new working tree
git worktree add .worktrees/backport-staging staging
# Navigate to the new working tree
cd .worktrees/backport-staging
# Create a new branch
git switch --create backport-29235-to-staging
# Cherry-pick the merged commit of this pull request and resolve the conflicts
git cherry-pick -x --mainline 1 f2fae82e3281b878e5e189534f2edec5ed6a9280
# Push it to GitHub
git push --set-upstream origin backport-29235-to-staging
# Go back to the original working tree
cd ../..
# Delete the working tree
git worktree remove .worktrees/backport-staging

Then, create a pull request where the base branch is staging and the compare/head branch is backport-29235-to-staging.
