refactor: deduplicate shared utilities across web scraper extractors

[chubes4]

Summary

• Move duplicated normalizeTime(), inferDate(), mergePageVenueData() into BaseExtractor shared methods
• Add loadDom() helper to eliminate repeated 5-line DOM bootstrap boilerplate across 7+ extractors
• Add fetchUrl() helper with logging for centralized HTTP fetch pattern
• Add resolveUrl() helper for relative URL resolution
• Fix Squarespace internal duplication: merge extractDateFromText() and parseTextDate() into one method using inferDateFromMonthDay()
• Replace copy-pasted implementations in RedRocks, Freshtix, RHP, Craftpeak, MusicItem, Microdata, Timely extractors

Why

The universal web scraper has 24 extractors across ~9,600 lines. Multiple extractors had identical implementations of time normalization, year inference, venue merging, DOM loading, and URL resolution. This consolidation makes the codebase more maintainable and reduces the surface area for bugs as we add new extractors and scale venue coverage.

Net change

+191 lines (shared utilities), -171 lines (duplicated code) = net +20 lines
