chore(layout): remove redundant shadcn Toaster — Sonner is the sole toast system

[dccakes]

📝 TLDR

Remove the unused shadcn/Radix <Toaster /> from the root layout; Sonner's <SonnerToaster> is already the sole active toast system.

📝 Description

The root layout mounted two toast providers side-by-side: the shadcn/Radix <Toaster /> and Sonner's <SonnerToaster>. A grep of the entire codebase confirmed that useToast() — the hook that feeds the Radix toaster — is only referenced in dead code under src/components/old_dashboard/. Every active feature drives toasts through Sonner's toast() directly. The Radix toaster was hydrating an unused viewport slot on every page load with no consumer.

This Change

• Removes import { Toaster } from '~/components/ui/toaster' from src/app/layout.tsx
• Removes the <Toaster /> JSX element from the root layout body
• <SonnerToaster richColors position='top-right' /> remains as the single, consistent toast provider

Recommendations Reviewed

#	Area	Finding	Size	Priority
1	Layout	Dual toast providers: shadcn <Toaster> mounted alongside Sonner but never invoked — dead hydration on every page	S	High
2	Events loading.tsx	Loading skeleton shows 1 toolbar button but the real page renders 2 ("General RSVP questions" + "Create Event") — layout shift on load	S	Medium
3	Vendor card	Star rating <button> has text-sm (~14 px) touch target — well below WCAG 44 px minimum; accessibility regression risk	M	Medium
4	Vendor card	Ratings breakdown popover has no click-outside handler — once opened it can only be closed by clicking the toggle button again	S	Low
5	quote-form / expense-form	toDateInputValue duplicated with divergent timezone behaviour (UTC slice vs. local getters) — silent date-off-by-one bug risk	M	Medium
6	Icon library consistency	Vendor detail panel mixes Lucide icons with raw Unicode emoji (★, ☆, ✕) — visual inconsistency across dark/light themes	M	Low

Selected Improvement

#1 — Remove redundant shadcn <Toaster /> from root layout

Why This Was Selected

• Smallest possible footprint (2-line deletion, zero risk of behaviour change)
• Eliminates dead React tree hydration on every page load
• Consolidates the app on a single toast system, removing a confusing artefact that could mislead future contributors into wiring up useToast
• Not covered by any of the 31 existing open draft PRs

Changes Made

Removed the Toaster import and JSX element from src/app/layout.tsx. SonnerToaster (already present) is the only active toast provider.

Files Changed

• src/app/layout.tsx — 2 lines deleted (import + JSX element)

Verification

• npx tsc --noEmit passes (only pre-existing baseUrl deprecation warning, unrelated to this change)
• Grep confirms useToast is referenced only in src/hooks/use-toast.ts, src/components/ui/toaster.tsx, and the dead old_dashboard components — no active feature depends on it

Future Recommendations

#	Area	Finding	Suggested action
2	Events loading.tsx	Skeleton shows 1 toolbar button; page renders 2	Add second <Skeleton className='h-9 w-36' /> to match "General RSVP questions" button
3	Vendor card	Star rating buttons have ~14 px touch target	Increase to min-h-[44px] min-w-[44px] or wrap in a larger hit-area container
4	Vendor card	Ratings breakdown panel has no click-outside close	Add useEffect with a mousedown listener or use a Radix Popover
5	quote-form / expense-form	toDateInputValue duplicated with UTC vs. local-time divergence	Extract a single shared util using date-fns format(date, 'yyyy-MM-dd') in local time
6	Vendor UI	Mixed Lucide icons and Unicode emoji (★, ☆, ✕)	Replace ★/☆ with <Star> from lucide-react (filled/outline variants); replace ✕ with <X> (already imported in vendor-card)

GitHub Issues Created

None — all remaining items are Small/Medium scope suitable for future daily improvement runs.

🧪 Testing

• Added/updated tests
• Manually tested functionality — confirmed no active component calls useToast; Sonner toasts continue to work

🧪 How to test as a user

1. Load any authenticated page (e.g. /vendors, /budget)
2. Trigger any action that produces a toast (add a vendor, update a quote, etc.)
3. Verify the Sonner toast appears top-right as before
4. Verify no second toast viewport or ghost element appears in the DOM

📚 Documentation

• No documentation changes needed

🎨 Style and code quality

• TypeScript check passes (npx tsc --noEmit)

📦 Dependencies

• No dependency changes
