Two user-reported bugs:
1. Promo spam: daily promo message from /start and the Promo menu
button stayed in chat forever. Now they auto-delete after 30s.
- new helper _delete_message_after()
- cmd_start schedules deletion of the daily promo
- cb_menu_promo sends promo as a SEPARATE ephemeral message
(instead of editing the main menu in place), so the menu stays
intact and only the promo self-destructs in 30s.
2. CRITICAL: 'install/change template from bot' was a stub that
silently corrupted /opt/gotelegram/config.json. cb_lite_domain
and cb_pro_confirm wrote a fake minimal config ({mode,template,
port,installed_at}) without secret/domain/mask_host, and showed
'[OK] installed!' — while never invoking install.sh, never
downloading the template, never touching nginx. Proxy link
generation then broke because secret was gone.
User symptom: 'устанавливал другой шаблон через бота и всё
повисло'.
Fix: both callbacks now refuse cleanly and route the user to the
CLI ('gotelegram' command → menu 1 → 1 or 7). Configuration is
NOT touched. Full non-interactive install/change from the bot is
left as future work.
Tested live on VPS:
- bot.py syntax OK (ast.parse on VPS)
- gotelegram-bot restarted, active
- corrupted config.json on VPS rebuilt from telemt TOML ground
truth (mode=lite, secret, port, mask_host=google.com)
- install.sh: fix {{NC}} -> ${NC} color escape on line 265
- bot.py: fix TOML parsing for telemt v3 [access.users] format
- bot.py: fix telemt config section [server].port instead of [config].listen_port
- telemt_config.sh: fix add_secret_to_config() for v3 format
- All frame boxes: correct 54-char width with emoji compensation
- Lite mode links now include ee-prefix + mask_host hex (fake-TLS)
- Added qrencode to ensure_deps() so QR codes work after fresh install
- Centralized link generation in generate_proxy_link()
- Fixed bot.py get_proxy_link() for lite mode ee-prefix
