chore: scrub internal-file ref from generated gRPC client headers

[satyakwok]

Both src/grpc-web/sentrix.ts and src/grpc-web/sentrix.client.ts had header blocks referencing founder-private/audits/...-grpc-service-proto-draft.md.

The upstream .proto in sentrix-labs/sentrix already carries the neutral phrasing 'internal Sentrix Labs gRPC service-proto draft (2026-05-05)'; the regenerated .ts here didn't pick up that change. This PR updates by hand to match — next regeneration via protobuf-ts will produce the same text.
