Add read-only web UI

Serves Pete's classified-story archive over HTTP alongside the Matrix
bot. Three sections (gaming/tech/politics), Animal-Crossing-vibe Tailwind
templates, day/night palette driven by the visitor's browser clock.
Web port configurable via web.listen_addr and ${PETE_WEB_PORT} in
docker-compose. Tailwind built in a node stage in the Dockerfile so
deployments don't need node at runtime.

+### Web UI
+
+Set `web.enabled: true` (default port `:8080`) to expose Pete's classified-story archive over HTTP. Three sections (`/gaming`, `/tech`, `/politics`) plus a landing page at `/`, all pulling from the `stories` table. Adding a section is two lines in `internal/web/server.go` (the `channels` slice) plus a matching theme color in `internal/web/static/css/input.css`.
+
+The frontend uses a small Tailwind build:
+
+```bash
+npm install
+npm run build:css            # produces internal/web/static/css/output.css
+# or for live editing:
+npm run watch:css
+```
+
+The Docker image runs the build automatically as a first stage, so deployments don't need Node.
+
+Front the server with a reverse proxy (Caddy, nginx, Traefik) terminating TLS for e.g. `news.parodia.dev → 127.0.0.1:8080`. The day/night palette is driven by the visitor's browser clock — no server-side timezone needed.

 ### Round-robin mode
 
 Set `posting.round_robin.enabled: true` to switch Pete from "post on classify" to a paced rotation. On each tick (`interval_hours`, default 4) Pete picks the newest unposted classified story routed to the next channel in sorted order, posting through the existing queue. Empty channels are skipped; the rotation pointer advances to whichever channel actually posted, and `last_channel` / `last_tick_at` are persisted so restarts don't reset the cycle. Rotating by channel (not by source) guarantees variety even when one channel has many more feeds than the others.
