Summary

Adds two new one-click service templates for SurrealDB:

• surrealdb (single-node with RocksDB persistence)
• surrealdb-with-tikv (distributed backend with PD + TiKV)

What changed

• Added templates/compose/surrealdb.yaml
• Added templates/compose/surrealdb-with-tikv.yaml
• Updated template manifests:
  • templates/service-templates.json
  • templates/service-templates-latest.json

Both templates include:

• Auth defaults using SERVICE_USER_SURREALDB / SERVICE_PASSWORD_SURREALDB
• Healthchecks
• Metadata (docs, category, tags, exposed port)

Notes

• This follows the issue request to support SurrealDB with and without TiKV.
• surrealdb uses RocksDB persistence via mounted volume.
