fix(ui): improve access-log filters and Caddy config readability

[RentnerKev]

Summary

Access logs now offer a searchable host dropdown, a status dropdown and debounced case-insensitive search. Filter actions align on desktop, and client IPs stay on one line.

Language settings and access-log country flags use country-flag-icons. The old language SVGs, flag-icons, geoip-country and its dependency override are removed. Web responses preserve stored country codes; the web service does not run GeoIP lookups.

Global Caddy Active config is indented and syntax-highlighted. Generated defaults, Preview and Reload are removed from the global editor; save/reset and background-fetch guards remain.

Outstanding work

The requested persistent country enrichment using only sapics/ip-location-db user-country.mmdb is not integrated yet. This PR must not be treated as complete for that requirement. No MaxMind database, accounts, credentials, updater container, external GeoIP API or Cloudflare country-header lookup is included.

⚠️ Unreviewed development preview

This image contains unreviewed pull-request code. It may contain bugs, breaking changes, incomplete or incompatible migrations, configuration errors, and changes that damage data or runtime state.

Do not use this PR preview image with production data.

Before testing:

1. Back up PostgreSQL.
2. Back up the complete RentnerProxy controller/runtime state in /var/lib/rentnerproxy, including certificates, private keys, ACME state, active configuration, last-known-good state, and trusted CA material.
3. Prefer a separate test database and separate Docker volumes.
4. Use an isolated Docker Compose project and avoid production port bindings.

Docker

docker pull ghcr.io/rentnerkev/rentnerproxy:pr-101-e0e61198bce6

Docker Compose

In a separate test copy of docker-compose.yml, replace the service image with:

image: ghcr.io/rentnerkev/rentnerproxy:pr-101-e0e61198bce6

Then use an isolated Compose project:

docker compose --project-name rentnerproxy-pr-101 pull
docker compose --project-name rentnerproxy-pr-101 up -d

The repository Compose file binds ports 80, 81, and 443; change those bindings or stop the production stack before testing.

This preview is intended only for testing this pull request and is not a production release.
