fix(ui): SettingsPage launch-at-login toggle — replace bounce-easing with ease-out-quart

Final impeccable detect cleanup. The launch-at-login toggle thumb in the
Tasks & Rituals section was using cubic-bezier(0.34, 1.56, 0.64, 1) — the
same overshoot bounce that was replaced in Toggle.svelte by commit
6469663. Match the convention here so all toggle animations use the
same exponential ease.

Single-line CSS change. Visual smoke not exercised because the dev
server is winding down between subagents; npm run build confirms the
file still compiles clean.
