Annotate read-only fields with google.api.field_behavior OUTPUT_ONLY

[qdrant-cloud-bot]

Summary

• Annotate documented read-only fields across the public API protos with [(google.api.field_behavior) = OUTPUT_ONLY], importing google/api/field_behavior.proto.
• Cover entity fields already described as read-only in comments (ids, timestamps, keys, caller audit fields, status/state, platform ceilings, etc.) and messages marked entirely read-only (e.g. ClusterState, SpaceEndpoint, BackupRestore, HybridCloudEnvironmentStatus).
• Regenerate Go/Python/TypeScript/OpenAPI bindings so OpenAPI exposes "readOnly": true for these fields.

Test plan

• make lint / make generate succeed
• Spot-check OpenAPI (readOnly: true) for ManagementKey, Cluster, Space, and Backup
• Confirm create/update request payloads are unchanged at the wire level (annotation-only change)
