feat: add Oryx (SRS) media streaming template

[Siumauricio]

Summary

Adds a template for Oryx (formerly SRS Stack), an all-in-one open-source video streaming server built on SRS, with a web console for managing streams, recording, forwarding, transcoding and virtual live streaming.

• Image: ossrs/oryx:5.15.20 (latest stable release on Docker Hub)
• Web console (port 2022) is routed through the Traefik domain
• State persisted in the oryx-data volume (/data)
• instructions.md covers the first-login password setup and the RTMP/SRT/WebRTC publish URLs

Port decision

RTMP, SRT and WebRTC are not HTTP protocols, so Traefik cannot route them through the domain. Following the precedent set by the poste.io template (which publishes its mail ports the same way), the streaming ports are published directly on the host, with a comment in the compose file explaining why:

• 1935:1935 — RTMP ingest/playback (TCP)
• 8000:8000/udp — WebRTC media transport (UDP)
• 10080:10080/udp — SRT ingest/playback (UDP)

Users publish streams against the server IP on these ports; HLS/HTTP-FLV playback and the console go through the HTTPS domain. This is documented in instructions.md.

Test evidence

Deployed on a Dokploy instance from this exact blueprint:

• Deploy: done (123s), container running
• GET / via the assigned domain → HTTP 200, <title>Oryx</title> (management console)
• GET /terraform/v1/mgmt/init → {"code":0,"data":{"init":false}} (first-run admin setup ready)
• Host port check: nc -vz SERVER_IP 1935 → connection succeeded (RTMP reachable)
• node build-scripts/generate-meta.js --check → 481 templates validated

Closes #300
