- SummaryPeriodFactory extracts daily/weekly/monthly period building, shared by scheduler and ad-hoc test action
- TelegramSectionRenderer converts SummarySection blocks (stats/heading/table/paragraph) to TelegramSummary fields
- TelegramChannel exposes sendRaw() with auto-chunking at 4000 chars for combined messages
- NotificationSettingsPage adds Stuur test-samenvatting ActionGroup with one entry per frequency that compiles every applicable contributor into a single Telegram message; daily contributors cascade up into weekly+monthly tests
- Modules without data render a placeholder line instead of being silently skipped, so the user sees that every module was tried
