Header-based auth made no difference; the real issue is the hotel network
firewall blocking HTTPS CONNECT tunnels on port 823. Reverted to URL-embedded
credentials (original approach). Fix requires DataImpulse to enable port 443.

Embedding credentials in the proxy URL (http://user:pass@host:port) was
breaking HTTPS CONNECT tunnels on the hotel network. Switching to separate
username/password fields (Playwright) and httpx.Proxy(auth=...) sends a
Proxy-Authorization header instead, which passes through correctly.
With DataImpulse IP whitelisting the 407 round-trip is skipped anyway so
there is no latency penalty.

DataImpulse takes ~14s to issue a 407 challenge from this network.
Passing credentials as separate Playwright proxy fields caused Chromium
to wait for that challenge before sending auth on every CONNECT request,
making scrapes consistently time out at 90s.
Embedding credentials directly in the proxy server URL makes Chromium
send Proxy-Authorization on the first CONNECT, bypassing the round-trip.

Proxy config, DataImpulse sticky-session username syntax, and Playwright/
httpx proxy builders now live in one place (services/proxy.py) instead of
being duplicated across the Booking.com backend and the /config/proxy test
endpoint. Both scrapers consume it.
- services/proxy.py: load_config/normalize (DB-authoritative, env fallback),
new_session_id, username, playwright_proxy, httpx_proxy_url
- PlaywrightLocalBackend delegates proxy building to the module
- get_scraper_backend factory uses proxy.load_config (one resolution path)
- test_proxy_config endpoint uses the shared URL builder; httpx proxies= ->
proxy= (forward-compatible, 0.28-safe)
- Direct booking-engine scraper (httpx) can now route through the same proxy,
gated by the direct_scraper_use_proxy flag (default off, plumbing ready)
Dead code removed: set_scraper_paused (never called — rotate-on-block
replaced pause-on-block), get_competitor_matrix / get_hotels_list /
update_hotel_tier (endpoints have their own SQL), unused PROXY_KEYS tuple.
