fix(atlas): gzip-compress responses so large country GeoJSON loads behind reverse proxies (#1262)

The admin-0 country GeoJSON served at /api/addons/atlas/countries/geo is
~30 MB uncompressed. With no compression in the request pipeline the
transfer aborts (~8s, net::ERR_FAILED despite a 200) behind reverse
proxies / Cloudflare Tunnel, so the Atlas map never colours visited
countries. LAN is unaffected.

Add the `compression` middleware to the shared applyGlobalMiddleware
pipeline (gzip brings ~30 MB down to ~4 MB). text/event-stream is
excluded so the /mcp StreamableHTTP (SSE) transport is not buffered.

Adds BOOT-008 asserting content-encoding: gzip on the geo endpoint.

Fixes #1254
