Wire up direct-rates column; remove dormant pause-on-block flow

Direct-rates sub-row in Market View was dead: the frontend filters
competitors on direct_hotel_id but /matrix and /hotels never returned it.
Add direct_hotel_id to both queries (+ HotelResponse), and only render the
"Direct" sub-row when a hotel actually has a non-null direct rate (was
rendering all-dashes on an empty {} object).

Remove the pause-on-block flow entirely — dormant since rotate-on-block
replaced it (nothing set booking_scraper_paused=true after set_scraper_paused
was dropped): is_scraper_paused, /config/unpause, the /scrape paused guard,
ScraperStatusResponse.paused/pause_until, and the frontend Paused badge +
Unpause button. Trim now-unused datetime import.
