Schema: migrate newbook_occupancy_report_data from single-row upsert to
snapshot model (drop unique constraint, add valid_from / last_verified_at)
matching the pattern used by newbook_current_rates.
Backend: sync_occupancy now inserts a new row only when occupied/available/
maintenance figures change, otherwise bumps last_verified_at. New endpoint
GET /bookability/occupancy-history/{category_id}/{date} returns the timeline.
Rate matrix query updated to DISTINCT ON for the multi-row table.
Frontend: clicking any cell in the Bookability matrix opens a modal with
two stacked Plotly charts — rate history per tariff (step lines, green/red
markers for available/unavailable) and occupancy pick-up over time.

Switches booking.com scraping from search-results page (Cloudflare-targeted)
to individual hotel property pages (not CF-protected). Each page load returns
all room types, all rate plan variants (room-only/B&B × refundable/non-ref ×
1-2 adults), and availability counts.
Key changes:
- New PlaywrightHotelPageBackend: proxy reuse until block, rotate on CF/WAF
- booking_scraper.py: _run_hotel_page_scrape(), scrape_hotel_date(),
_scrape_hotels_concurrent() — sharded by hotel so one proxy session covers
all dates for one hotel (looks human)
- schema.sql: ADD COLUMN rate_plan_id, max_persons on booking_com_rates
- competitors API: filter max_persons=2, order by rate_gross ASC as tiebreaker
so DISTINCT ON returns cheapest 2-adult rate from latest batch

Free-text ss= destination resolution is non-deterministic: tonight's
30-day run resolved "Stow on the Wold" to St. Wolfgang, Austria for 8 of
30 dates, saving Salzkammergut hotel rates into the matrix. dest_id +
dest_type=city in the search URL pins the destination.
- booking_scrape_config gains a dest_id column (idempotent ALTER)
- scrape_location_search/_build_search_url thread dest_id through
- /config/location accepts dest_id

Location-search results aren't a fixed hotel set — a sold-out hotel drops
out and its last 'available' rate would remain the latest row for that
date, reading as a live price and skewing market averages. On each
successful per-date scrape, insert a NULL-rate 'not_listed' row for every
active hotel missing from the results (skipped if the parse found nothing,
which indicates scraper fault not absence). Failed/blocked scrapes write
nothing, so genuinely-stale data remains distinguishable by scraped_at.
Also: fix the DOW analysis to pick latest-then-filter so a not_listed
latest row drops the date instead of resurfacing an older rate, and widen
booking_com_id to VARCHAR(255) (some Booking slugs exceed 50 chars).

Scraped room descriptions exceed VARCHAR(100) (StringDataRightTruncation),
and the failed insert poisoned the transaction so every subsequent save in
the batch died with InFailedSqlTransaction — scrapes reported success with
0 rows saved. Widen the column (with ALTER for existing tables) and roll
back after a failed save.

- schema defined gross_rate/net_rate but every query (fetch job,
bookability, competitors) uses rate_gross/rate_net — rename the
columns, with an idempotent DO-block migration for existing tables
- roll back the session when a date fails so one bad statement no
longer poisons the whole sync run (every subsequent write was dying
with 'current transaction is aborted')
