* chore(deploy): trust proxy headers + document HTTPS env vars
- uvicorn: add --proxy-headers --forwarded-allow-ips='*' so the app honors
X-Forwarded-Proto/Host from a TLS-terminating reverse proxy (Caddy,
Cloudflare Tunnel, nginx, LB). Without this the app saw every request as
plain HTTP and built redirect/OAuth URLs from the raw Host, which is
fragile behind a proxy.
- .env.template: document DOMAIN (enables Secure cookie flag) and new
SERVER_URL (deterministic base URL for OAuth callbacks and external
links). Grouped under a dedicated HTTPS / REVERSE PROXY section.
* chore(deploy): add proxy header flags to Dockerfile CMD and Kamal config
Matches the docker-compose changes so non-compose deployments (docker run,
Kubernetes, ECS, Kamal) also trust X-Forwarded-Proto/X-Forwarded-For.
* fix(auth): align Google OAuth cookie Secure flag with password/email providers
Google OAuth set the access_token cookie Secure flag based on the TESTING env
var, while password and email providers use DOMAIN. This meant the DOMAIN
env var (now documented in config/.env.template) did not actually control
Secure for Google cookies. Align all three providers on DOMAIN so the
documented behavior holds consistently.
Update project structure, architecture diagram, key implementation
details, development commands, and extensibility docs.
Add extract service to docker-compose.yml for one-shot extraction.
