- Change Helmet default from no-referrer to strict-origin-when-cross-origin
so browsers send the origin on cross-origin requests, allowing Google Maps
API key restrictions by HTTP referrer to work correctly
- Document HSTS_INCLUDE_SUBDOMAINS in all deployment artifacts:
.env.example, docker-compose.yml, README.md, unraid-template.xml,
charts/values.yaml, charts/configmap.yaml, wiki/Environment-Variables.md
Adds the complete TREK documentation wiki covering installation,
trip planning, admin panel, MCP/AI integration, addons, and operations.
Also fixes encrypt-at-rest gaps: mapbox_access_token, Synology
credentials, per-user webhook/ntfy tokens, and photo passphrases
are now rotated by migrate-encryption.ts and stored encrypted via
settingsService.
