feat: migrate geolocation lookup to ipinfo.io with MaxMind support (#177)

* refactor: replace IP2Location with MaxMind GeoIP2

Migrated the geoblock service from `ip2location-go` to `geoip2-golang`
to
improve accuracy and support modern MaxMind database formats.

- Updated `GeoData` structure to map standardized country codes and
ASN/ISP info.
- Refactored `geoBlocker` service to use native `net.IP` parsing.
- Updated `metrics` and `dispatcher` tests to reflect the new API
signature.

* refactor: migrate geolocation lookup to MaxMind

- Replaced IP2Location with `maxminddb-golang/v2` for geolocation and
ASN lookups.
- Updated `GeoData` structure to map to MaxMind database fields.
- Added `dns_provider_count` Prometheus metric to track traffic by ASN
and ISP provider.
- Refactored `GeoIpLookup` service for better type safety and
performance.

* refactor: rename IP2Location config to IPInfo

Updated configuration flags and environment variables to reflect the
migration from IP2Location to ipinfo.io for GeoIP data.

* refactor: update client metrics delimiter

Change the delimiter used in `TopClients` metric keys from a comma (`,`)

to a pipe (`|`) to prevent parsing conflicts with metadata containing
commas (e.g., ASN n... (continued)
