Add initial files and database migration for ticket pricing system

- Created new directories and index files for controls, factory, and views.
- Added .htaccess files for URL rewriting in layout and images directories.
- Included a logo image in the layout/images directory.
- Implemented load_prices.php to load ticket prices from the database into settings.
- Developed admin panel settings page for enabling ticket sales.

+# CLAUDE.md
+
+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+
+## Project Overview
+
+Online ticket sales system for **Kompleks Turystyczny Brzezovka** (amusement park in Kolbuszowa, Poland). Handles ticket purchase, shopping cart, Przelewy24 payments, QR code generation, invoice issuing (via fakturowo.pl API), and a QR ticket scanner for staff.
+
+Live at: `bilety.brzezovka.pl`
+
+## Architecture
+
+Custom PHP MVC without a framework. No Composer — all dependencies are vendored in `libraries/`.
+
+### Request Flow
+
+1. `.htaccess` rewrites URLs as `/{module}/{action}/{params}` → `index.php?module=X&action=Y&...`
+2. `index.php` bootstraps: autoloader, config, DB connections (Medoo + RedBeanPHP), session
+3. `\view\Site::show()` → `\controls\Site::route()` resolves `module`/`action` to a controller method via `\controls\{Module}::{action}()`
+4. Controllers return rendered HTML via `\Tpl::view('template-name', $vars)`
+
+### Autoloader Convention
+
+`spl_autoload_register` maps namespaced classes to files:
+- `\controls\Tickets` → `autoload/controls/class.Tickets.php`
+- `\factory\Tickets` → `autoload/factory/class.Tickets.php`
+- `\view\Site` → `autoload/view/class.Site.php`
+- `\S`, `\Tpl`, `\DbModel`, `\Html` → `autoload/class.{Name}.php`
+
+### Layer Responsibilities
+
+| Layer | Namespace/Dir | Role |
+|-------|--------------|------|
+| Controllers | `autoload/controls/` | Handle actions, coordinate logic, return rendered views |
+| Factory (Services) | `autoload/factory/` | Business logic, DB queries, data processing |
+| Views | `autoload/view/` | Layout assembly (wraps controller output in site layout) |
+| Templates | `templates/` | PHP template files rendered by `Tpl::view()` |
+| Core classes | `autoload/` (root) | `S` (utility/session), `Tpl` (templating), `DbModel` (active record), `Html` (form helpers) |
+
+### Key Modules
+
+| Module | Controller | Purpose |
+|--------|-----------|---------|
+| `tickets` | `controls\Tickets` | Public ticket shop: browse, add/remove from cart, checkout, payment |
+| `apanel` | `controls\Apanel` | Admin panel: order list, order editing, ticket validation |
+| `scanner` | `controls\Scanner` | QR code scanner for on-site ticket verification |
+| `users` | `controls\Users` | User login/logout, settings, permissions |
+
+### Database
+
+MySQL via two ORMs used in parallel:
+- **Medoo** (`$mdb` global) — primary query builder for tickets/orders
+- **RedBeanPHP** (`\R::`) — used in cron jobs (CEIDG import)
+
+Main tables: `orders`, `order_tickets`, `users`
+
+### Entry Points
+
+| File | Purpose |
+|------|---------|
+| `index.php` | Main app entry (web requests) |
+| `ajax.php` | AJAX endpoint (same autoloader, Medoo only) |
+| `api.php` | API endpoint (autoloader + Medoo + PHPMailer + RedBeanPHP) |
+| `cron.php` | Scheduled tasks (email reminders, CEIDG import) |
+
+### External Integrations
+
+- **Przelewy24** — payment gateway (merchant config in `config.php`)
+- **fakturowo.pl** — invoice/receipt generation via API
+- **PHPMailer** — email sending (SMTP via `bilety@brzezovka.pl`)
+- **phpqrcode** — QR code generation for order hashes
+
+## Frontend
+
+- Bootstrap 5.2, jQuery 3.6, Font Awesome 6.1
+- SCSS in `layout/style-scss/` compiled to `layout/style-css/style.css`
+- SCSS compile comment: `// out: ../style-css/style.css, compress: true, sourceMap: true` (Live Sass Compiler)
+- DataTables for admin order list
+- html5-qrcode for scanner
+- Datepicker for ticket date selection
+
+## Key Conventions
+
+- All controller methods are `static public` and accessed via URL routing
+- Global `$settings`, `$mdb`, `$user` are used throughout (no DI)
+- Ticket config (prices, types, dynamic pricing) lives entirely in `config.php`
+- Session-based shopping cart stored at `$_SESSION['basket']`
+- Admin auth is a single shared password (`$settings['admin-password']`), stored in session as `$_SESSION['user']`
+- Template rendering: `\Tpl::view('path/template-name', ['key' => $value])` — variables accessible as `$this->key` in templates
+- AJAX responses: controllers `echo json_encode(...)` then `exit;`
+
+## Development
+
+- No build system, test framework, or package manager
+- SCSS compilation: use VS Code "Live Sass Compiler" extension (configured via first-line comment in `style.scss`)
+- Deployment: FTP sync (`.vscode/ftp-kr.sync.cache.json` present)
+- PHP version: compatible with PHP 7.4+ (no typed properties, uses legacy autoload pattern)
+- Timezone: `Europe/Warsaw`
+- Language: Polish (all UI text, comments, variable names mix PL/EN)
