v0.5.3

xrat v0.5.3

GeoIP fixes

• geoip: endpoint location is now derived from the server address instead of
  the proxy connection. Tested configs previously stored loopback_ipv4 because
  the real-delay stage read the local proxy address (127.0.0.1); the TUI table
  Country column showed - while the detail card showed loopback_ipv4.
• TUI: placeholder locations are treated as missing geo, so existing
  poisoned rows self-heal from the config address off the critical path without
  affecting first-paint time.

Upgrade notes

• No new database migrations in this release.
• Re-run xrat test (or let the TUI re-enrich in the background) to replace any
  loopback_ipv4 locations stored by earlier versions with real geo.
