sulthan bcc6b45515 feat(backend): Discord OAuth login with DB-backed sessions (#23) (#31)
Implements #23 per ADR-0002.

- Discord authorization code grant (identify + guilds.members.read), form-encoded token exchange
- Guild membership gate via the single-guild endpoint; optional DISCORD_REQUIRED_ROLE (empty default)
- Owner Discord ID is the only identity allowed to sign in
- Sessions are DB rows with opaque random ids; cookie carries only the id; expiry enforced; delete = revoke
- HMAC session signing, derived key, and WEB_PASSWORD removed; no replacement signing secret
- Login rate limiting preserved on the callback
- Full flow tested through the real router against a local Discord stub (DISCORD_API_BASE)
- Env: DISCORD_CLIENT_ID/_CLIENT_SECRET/_GUILD_ID/_REQUIRED_ROLE/_API_BASE/_REDIRECT_URI; docs updated

go test ./... passes.

# --- Web UI (Discord OAuth) ---
# Sign-in is a Discord authorization code grant (ADR-0002): the owner signs in
# with Discord, and guild membership gates access. Create the application at
# https://discord.com/developers/applications and register the exact callback
# URL ($BOOKMARK_WEB_HOST/auth/discord/callback) as an OAuth2 redirect.

# Subdomain Traefik routes to the browser UI (required by the prod override).
# Left commented on purpose: an example value here would be a silent
# wrong-hostname fallback, and Traefik would publish the UI router on a domain
# you do not own. The same container also answers on BOOKMARK_API_HOST for the
# userscript's API.

# --- Latest-chapter poller ---
# The backend re-checks each bookmarked series' newest published chapter on its
# own schedule, so latest_chapter stays fresh even when you never open the manga
# sites. This runs in parallel with the userscript's own in-browser check.
# Set to 0 to turn it off entirely.
# LATEST_CHAPTER_POLL_ENABLED=1
#
# Two independent clocks. COOLDOWN is how long one series rests between checks;
# INTERVAL is how often the poller wakes up and looks for series past that
# cooldown. Shortening INTERVAL cannot shorten a COOLDOWN.
# LATEST_CHAPTER_POLL_COOLDOWN=1h # per series, floor 15m
# LATEST_CHAPTER_POLL_INTERVAL=10m # how often to wake
# LATEST_CHAPTER_POLL_BATCH=14 # series per wake
# LATEST_CHAPTER_POLL_STAGGER=20s # delay between fetches in a batch
#
# Uses a ticker, not an immediate first run: the first poll happens one
# INTERVAL after startup, not at startup. A container restarting more often
# than INTERVAL never polls.
#
# BATCH x (COOLDOWN / INTERVAL) series hold the cooldown cadence — 84 with these
# defaults. Beyond that the cadence stretches uniformly rather than breaking;
# raise BATCH or lower INTERVAL. Keep BATCH x STAGGER under INTERVAL.
# Headless-shell CDP endpoint for sites behind a JavaScript challenge (kagane).
# Unset disables browser polling; those sites then rely on the userscript alone.
# Leave commented — the compose files' own default (ws://172.28.0.10:9222) is
# correct. Do NOT set this to the "headless-shell" DNS name: Chrome's DevTools
# HTTP handler 500s any /json/version request whose Host header isn't an IP or
# "localhost", which silently breaks every kagane poll.
