Enhance Telegram bot UI with YTD comparison, 12-month evolution, and improved navigation

- Add YTD year-over-year comparison table for cash flow evolution
- Extend monthly evolution from 6 to 12 months with dynamic year extraction
- Simplify monthly view to show only Net values aligned with YTD table
- Upgrade client/supplier display from Top 5 to Top 10 with alphabetical sorting
- Remove Refresh and Export buttons from dashboard and evolution views
- Add get_trends() API method for 12-month historical data from backend
- Fix default years to 2025/2024 for accurate YTD calculations

Changes:
- client.py: New get_trends() method calls /api/dashboard/trends endpoint
- helpers.py: Rewrite get_cashflow_evolution_data() to use trends and calculate YTD
- formatters.py: Complete redesign with YTD table and simplified 12-month Net view
- menus.py: Alphabetical sorting for clients/suppliers, removed refresh buttons
- handlers.py: Disabled refresh/export buttons on dashboard and evolution views
