Verify start-page info-section content per TZ Table 8 + Table 9

Add assertion tests confirming both OnlineBoardStartPage and ScheduleStartPage
render the required info-section headings and content blocks per TZ specifications.

OnlineBoardStartPage (TZ Table 8):
- Heading: 'Что такое Онлайн-табло и что я могу в нем увидеть?'
- 4 info blocks: Актуальная информация, Информация об услугах, Купить билет, Расписание

ScheduleStartPage (TZ Table 9):
- First heading: 'Как пользоваться расписанием?' + 4 info blocks
- Second heading: 'Возможности расписания' + 2 capabilities blocks
- Blocks 5-6 (Купить билет, Расписание) now rendered under capabilities heading

Tests added:
- OnlineBoardStartPage: 6 new assertions (4.1.6-R-info-heading through 4.1.6-R-popular)
- ScheduleStartPage: 8 new assertions (4.1.7-R-info-heading-1 through 4.1.7-R-popular)
