feat: add undo toast for Reset all settings button

[vdadheech]

Saves a snapshot of current settings before reset and shows a 5-second undo toast. Clicking Undo restores the previous state. Follows the Gmail-style 'snackbar undo' pattern instead of a blocking confirm dialog.

Hey @vdadheech! This PR has merge conflicts with main that need to be resolved before review. Please rebase:

git fetch origin
git rebase origin/main
# resolve any conflicts
git push --force-with-lease

Once rebased and CI (build/lint/typecheck) passes, the undo toast feature will be reviewed. Thanks!

[magic-peach]

Hey @vdadheech! The undo toast pattern for the reset button is a clever UX idea (Gmail-style snackbar).

However, there are blockers:

1. package-lock.json added — This is a hard reject. This project uses bun.lock exclusively. package-lock.json must be removed from the PR. It's also in the .gitignore.

2. Empty PR description — Please fill in the related issue number, contribution level, and checklist.

3. No CI checks — Build, lint, and typecheck haven't run.

4. Merge conflicts — The PR is conflicting with main.

To fix:

• Remove package-lock.json from your branch: git rm package-lock.json && git commit
• Fill out the PR template
• Rebase on latest main to resolve conflicts and trigger CI

Once these are fixed, the feature can be properly reviewed.
