Switch Playwright to Firefox to evade Booking.com Chromium JA3 fingerprint detection

Browse source 
Booking.com detects headless Chromium via TLS ClientHello fingerprint (JA3)
and immediately flags the residential proxy IP on first contact. Firefox has
a different TLS fingerprint and GREASE extensions that aren't yet flagged.
Image blocking via Firefox preference (permissions.default.image=2) replaces
the Chrome --blink-settings flag. Dockerfile updated to install both browsers.
