Old Stocks block_id has 0 in position 2 (not the persons count) so all
its rates were stored as max_persons=0 and deprioritised in the matrix.
Now reads max_persons from the visible 'Max persons: N' span (matching
the original scrapy spider), with aria-label/title fallback. block_id
segment 2 is unreliable across different hotel layouts.
Also treat max_persons=0 as unknown in the matrix ORDER BY priority.

Add UA rotation (8 real Chrome UAs), random viewport, en-GB locale,
Europe/London timezone, stealth browser args to suppress automation
signals, and a per-context init script masking navigator.webdriver,
plugins, and chrome runtime.

The previous approach walked siblings from [id^="room_type_id_"] anchors
and only processed rows with js-rt-block-row class, causing the first rate
row of some room types to be silently skipped when that class was absent.
Now iterates all #available_rooms tbody tr rows with data-block-id (same
strategy as the original scrapy spider), using the room_type_id_ element
presence to identify room names only on the first row, with fallback to the
stored name for subsequent rows of the same room type.

_proxy_enabled() was checking cfg.get('server') but load_config() returns
{host, port, username, ...} — no 'server' key. Server URL is built by
proxy_util.playwright_proxy(). This meant proxy was silently disabled
and _proxy_kwargs() would also KeyError if called.
- _proxy_enabled() now delegates to proxy_util.is_enabled() (checks host+username)
- _proxy_kwargs() now calls proxy_util.playwright_proxy() with credentials
embedded in the URL (avoids 14s DataImpulse 407 round-trip)
- _get_context() generates a sticky session_id per context so each worker
gets a distinct residential IP lane

- Scraper: extract max_persons from block_id (3rd segment) instead of cell text; cell[0] was picking up the price value (e.g. 189/166) causing the max_persons=2 filter to exclude all scraped rows and show "No rates available" in snapshot
- MarketView: add namelength: -1 to Plotly legend to prevent label truncation; increase bottom margin from 50→65 and legend y from -0.25→-0.3

The 'We have X left' scarcity indicator only appears when availability is
low (typically ≤5). The quantity <select> dropdown in the booking form
always shows 0..N where N = actual available qty (capped at 10).
Extract max option value from the <select> in the last table cell per rate
plan row, falling back to regex parsing of the cell text if the select
isn't rendered, then to the scarcity text as a last resort.
Stored in both rooms_left and available_qty on RateData.

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
Enable via Settings → Scraper Backend → playwright_hotel_page
