chore!: remove deprecated name and namespace fields from frontier permission protos

[whoAbhishekSah]

Summary

Removes the deprecated name and namespace fields from the frontier Permission message (models.proto) and PermissionRequestBody (admin.proto). The key field (service.resource.verb) is the sole way to express a permission's identity in both requests and responses. Final proto step of raystack/frontier#1782.

Why this is safe

• frontier stopped reading the request fields (refactor(api): require permission key in create and update requests frontier#1885) and no longer needs the response fields since key round-trips losslessly (fix(permission): make the response key lossless and migrate its readers frontier#1887).
• Field numbers and names are reserved, so they cannot be reused and buf breaking (WIRE) passes.
• On the wire, proto3 ignores unknown fields: an old client that still sends name/namespace gets the same behavior it gets today (the server no longer reads them). Clients that read the removed response fields must move to key; frontier will call this out in its release notes.

Changes

• raystack/frontier/v1beta1/models.proto: drop Permission.name (2) and Permission.namespace (6); reserve the numbers and names; document key.
• raystack/frontier/v1beta1/admin.proto: drop PermissionRequestBody.name (1) and .namespace (2); reserve the numbers and names.

Test Plan

• buf lint passes
• buf breaking --against main passes

📝 Walkthrough

Walkthrough

The protobuf definitions remove the deprecated name and namespace fields from PermissionRequestBody and Permission. Their field numbers and names are reserved for compatibility. Permission also removes validation for name and documents the three-part key format.

Merge Risk: ⚪ Minimal · up to b4b46

This change removes deprecated permission fields while preserving reserved wire identifiers and using the existing key field as the identity; no actionable merge-blocking risk remains after normal checks and review.
