feat: Complete API authentication system with email & Telegram support

- Add email/password registration endpoint (/api/v1/auth/register) - Add JWT token endpoints for Telegram users (/api/v1/auth/token/get, /api/v1/auth/token/refresh-telegram) - Enhance User model to support both email and Telegram authentication - Fix JWT token handling: convert sub to string (RFC compliance with PyJWT 2.10.1+) - Fix bot API calls: filter None values from query parameters - Fix JWT extraction from Redis: handle both bytes and string returns - Add public endpoints to JWT middleware: /api/v1/auth/register, /api/v1/auth/token/* - Update bot commands: /register (one-tap), /link (account linking), /start (options) - Create complete database schema migration with email auth support - Remove deprecated version attribute from docker-compose.yml - Add service dependency: bot waits for web service startup Features: - Dual authentication: email/password OR Telegram ID - JWT tokens with 15-min access + 30-day refresh lifetime - Redis-based token storage with TTL - Comprehensive API documentation and integration guides - Test scripts and Python examples - Full deployment checklist Database changes: - User model: added email, password_hash, email_verified (nullable fields) - telegram_id now nullable to support email-only users - Complete schema with families, accounts, categories, transactions, budgets, goals Status: Production-ready with all tests passing

+## 🔐 Authentication Flows
+
+### Flow 1: Quick Telegram Registration (Fastest - 1 step)
+```
+User sends /register to bot
+    ↓
+Bot → POST /api/v1/auth/telegram/register
+    ↓
+Bot ← JWT Token
+    ↓
+Bot stores in Redis
+    ↓
+✅ User ready to use immediately
+```
+
+### Flow 2: Link Existing Account (3 steps)
+```
+User sends /link to bot
+    ↓
+Bot → POST /api/v1/auth/telegram/start
+    ↓
+Bot ← Binding code
+    ↓
+User clicks link, logs in with email
+    ↓
+Frontend → POST /api/v1/auth/telegram/confirm
+    ↓
+Bot → POST /api/v1/auth/token/get
+    ↓
+Bot stores JWT
+    ↓
+✅ Account linked and ready
+```
+
+### Flow 3: Email Registration (for Web users)
+```
+User → Web Frontend
+    ↓
+User registers with email/password
+    ↓
+Frontend → POST /api/v1/auth/register
+    ↓
+Frontend ← JWT tokens
+    ↓
