feat(quartz-relay): rename + promote to a real Nostr relay

Renames :quartz-test-relay to :quartz-relay and promotes it from a
test-only fixture to a real, runnable Nostr relay that just happens
to also be used in tests.

Two transports now share the same `Relay` core:

- `RelayHub` + `InProcessWebSocket` — no socket, fastest path; ideal
  for unit tests inside one JVM.
- `LocalRelayServer` — Ktor `embeddedServer` (CIO engine) listening
  on a real `ws://` port. Use for `cli` interop tests, Android
  instrumented tests, or running the relay standalone.

NIPs implemented (all driven through production `NostrClient` in the
new `LocalRelayServerTest`):

- NIP-01 wire protocol (REQ/EVENT/EOSE/CLOSE) over real WebSockets
- NIP-09 deletion (via existing `DeletionRequestModule`)
- NIP-11 relay info doc — `RelayInfo` wraps the existing
  `Nip11RelayInformation` model and is served on HTTP GET when
  `Accept: application/nostr+json` is requested. Loadable from a
  JSON config file via `RelayInfo.fromFile(...)`.
- NIP-40 expiration (existing `ExpirationModule`)
- NIP-42 AUTH (existing `FullAuthPolicy`, opted-in via the
  `--auth` flag in the standalone runner)
- NIP-45 COUNT
- NIP-50 search via the existing FTS index
- NIP-62 right-to-vanish (existing module)

Adds a standalone runner: `./gradlew :quartz-relay:run --args="--port 7447 --verify"`
binds the relay to a real port. Flags: --host, --port, --path,
--info <file>, --db <file>, --auth, --verify.

Test-only event generators moved to a clearly-named
`com.vitorpamplona.quartz.relay.fixtures` package so they're still
shareable with consumer tests without polluting the production API.

Adds `LocalRelayServerTest` covering NIP-01/11/42/45/50 over a real
loopback WebSocket. Existing 11-test `Nip01ComplianceTest` (in-process
transport) continues to pass.
