A full rewrite and modernization of the package.

Livewire 3 checkout — coin picker with live search, QR code, copy-to-clipboard address.
Real-time payment modal — polls CoinPayments until complete (configurable poll_interval) with a live countdown timer.
Partial-payment awareness — shows the remaining amount to send instead of a confusing "waiting" state.
Standalone admin panel (gate protected):
- Wallet dashboard with per-coin balances and fiat valuation (testnet coins excluded via fiat_exclude).
- Withdrawals — history, detail, single-refresh and cancel.
- Transactions — full table with search, status/coin/date filters, sortable columns and pagination.
coinpayment:sync artisan command — poll pending transactions when IPN isn't reachable; auto-expires overdue unpaid transactions. Schedulable via cron.
Configurable transaction listener (config('coinpayment.listener')) — point at any job or disable it.
Theming — customize colors via config('coinpayment.theme'); pages never inherit the host app's CSS.
Mobile-friendly admin with a bottom navigation bar.
Configurable admin guest redirect (config('coinpayment.admin.redirect')).

Requires PHP 8.2+ and Laravel 11, 12 or 13.
Frontend rebuilt with Livewire 3 + Alpine and Tailwind via CDN — no Node/Vue/webpack build step.
All CoinPayments API calls now use Laravel's Http client with TLS verification (previously raw cURL with SSL verification disabled).
IPN callbacks are verified with HMAC-SHA512 and return proper responses; the IPN route is auto-excluded from CSRF.
Transaction payloads are stored as JSON instead of PHP serialize.
Eloquent model modernized (casts() method, anonymous-class migrations).
items is now optional when creating a transaction; when provided, subtotals must equal amountTotal.
License changed to a source-available, open-core model: free for development; premium features require a paid license in production/staging (see Premium features).

Legacy frontend stack: axios, jQuery, Bootstrap, Vue 2, laravel-mix, moment, sweetalert and the entire Node build pipeline.
Vestigial files and dead legacy console commands left over from v3.

Withdrawal endpoints returned an undefined variable instead of the API response.
IPN handler now always returns an explicit HTTP response.
env() calls replaced with config() for cache-safe configuration.
