fix(quartz): accept legacy nostrnests tag names on kind-30312 read

The first-party nostrnests web client (NestsUI-v2) emits kind-30312
events using NIP-53 *streaming-event* tag names rather than the
kind-30312 names defined by NIP-53 itself. Confirmed against
`nostrnests/nests/NestsUI-v2/src/components/EditRoomDialog.tsx` and
`useRoomList.ts`:

  - room name: `title`     (NIP-53 spec for 30312: `room`)
  - MoQ relay: `streaming` (NIP-53 spec for 30312: `endpoint`)
  - moq-auth:  `auth`      (NIP-53 spec for 30312: `service`)
  - status:    `live`      (NIP-53 spec for 30312: `open` / `private`
                            / `closed` / `planned`)

Our parsers followed the NIP-53 spec, so events from the production
nostrnests web app fell through to status=null, which `checkStatus`
then surfaced as "Ended" in the live-rooms UI. Add legacy-alias
acceptance to all four parsers — read-side only; we still emit the
canonical NIP-53 forms, matching EGG-01.

Per-tag changes:
  StatusTag:      "live" → OPEN, "ended" → CLOSED
  RoomNameTag:    "title" alias → room
  EndpointUrlTag: "streaming" alias → endpoint
  ServiceUrlTag:  "auth" alias → service

No emit-side changes; no spec change.
