fix: route geo-blocker log entries to access.log

The caddy-blocker plugin already emits "request blocked" log entries
for geo/IP blocks, but they were going to Caddy's default log (stdout)
instead of /logs/access.log because http.handlers.blocker was not in
the access log include list. The existing log parser and dashboard were
already wired up to count these — they just never received the data.
