v1.7.0: refactor max_bot to flat structure, add VCF+UserModel+NLP history context, portal pages and proxy fixes

- Refactored max_bot from nested packages to flat module structure
- Q2: Extended BotUser model (patronymic, email, org, address, vcf_raw, contact_hash, phone_verified, email_verified, last_interaction, total_conversations, total_tickets)
- Q2: VCF parser (FN, N, TEL, EMAIL, ORG, ADR), upsert on re-contact, NLP history context (_get_user_history_context -> YandexGPT)
- Q1: Broadcast preview modal with 10s confirmation timer
- Q3: CSS var(--white)->var(--bg-card), var(--text)->var(--text-primary)
- Q4: bot_settings showNotification(), editable max_bot_id
- Q5: Webhook secret passthrough via X-Max-Bot-Api-Secret
- Masking sensitive keys, dialog_cleared handler, migrate via _add_column_if_not_exists()
- Rate limit (asyncio.sleep 0.5 per 10), dead code removed, conv.intent context in contact.py
- Portal pages: bot_consent, bot_kb (edit), bot_settings, bot_test, bot_tickets, portal_settings
- Tests: 21/21 passing, added test_yandex_gpt.py, test_email_sender.py
- Deploy: deploy_full.sh, schema.sql, seed_knowledge_base.sql
