Feature: Restaurant Parser Improvements

Source: TODO.md lines 19-29

Implementation Notes

Improve the reliability and accuracy of restaurant menu scrapers/parsers.

Sub-tasks from TODO.md:

Sladovnická:

Unnecessary initial index validation – the specific day's date is also in the meal table itself (see TODO in parser)

U Motlíků:

Validate that the input date is included in the range shown above the table (e.g., '12.6.-16.6.')
Menu is fetched once per day, but theoretically once per week would suffice (assuming it doesn't change mid-week)

TechTower:

Validate that the input date is included in the range shown above the table (typically 'Obědy 12. 6. - 16. 6. 2023 (každý den vždy i obědový bufet)')
Menu is fetched on the first request of the day, but the website often updates only during Monday morning, so the displayed menu may be outdated
- The page doesn't send a last-modified header, so that can't be relied upon
- No clear solution other than more frequent scraping of the entire page

Approach:

Review each parser for the issues listed above
Add date range validation to U Motlíků and TechTower parsers
Refactor Sladovnická parser to use date from the meal table directly
Consider a smarter caching/refresh strategy for TechTower (e.g., re-scrape every few hours on Monday mornings)
