feat(email_domains): Add domain validation and improve domain management

- Add validate_domain_format() function with comprehensive domain format validation
* Validates domain structure (must contain dot, valid characters, proper TLD length)
* Normalizes domain format (adds @ prefix, removes quotes/special chars)
* Returns validation status with detailed error messages
- Update add_email_domains() to use new validation function
* Track invalid domains separately in return tuple
* Return (added, skipped, invalid, total) instead of (added, skipped, total)
* Improve error handling and domain normalization
- Add get_file_domains_count() function to retrieve txt file domain count
- Update clear_email_domains() to return count of cleared domains
- Enhance telegram_bot.py command menu organization
* Add s2a command handler and callback for S2A service management panel
* Reorganize bot commands with category comments (基础信息, 任务控制, 配置管理, etc.)
* Add missing commands: clean_errors, clean_teams, iban_list, iban_add, iban_clear, domain_list, domain_add, domain_del, domain_clear, team_fingerprint, team_register, s2a
- Update domain_add command help text with format requirements
- Improve code documentation and consistency across both files
