fix: strip conditional headers in bot-block-proxy to fix CalDAV sync

Browse source 
nginx's not_modified_filter evaluated If-Match headers forwarded by
Traefik's forwardAuth, returning 412 and breaking CalDAV VTODO updates
from macOS/iOS Reminders. Switch to OpenResty and clear conditional
headers with Lua before proxy processing.
