fix(ai): preserve full RPC paths with the native client

[izadoesdev]

AI tool calls built a separate client for each subrouter, so middleware received create instead of links.create. That dropped the namespace from tracking and caused the existing mutation-audit gate to skip these calls.

Use oRPC's native client for the full router. Delete the one-consumer client adapter, three type casts, and two forwarding helpers. Keep the lazy router import, authentication context, dry-run guard, cancellation, validation, and error mapping. Existing audit and tracking middleware now receive the complete procedure path.

Validation: reproduced the missing path with the installed SDK and a failing regression test before the fix. All six focused RPC checks now pass, including strict AbortSignal identity. Root lint, 33 type/build tasks, and 27 test tasks pass; independent diff review is clear. Runtime checks use synthetic procedures and mocks. One file deleted, no new files.

Scope: AI tool RPC invocation only. No dependency on or file overlap with #790 or #751; RPC context, billing implementation, and business-context handlers are unchanged.

Summary by cubic

Fixes AI tool RPC calls so middleware receives the full procedure path (links.create) instead of just create. Previously, a separate client was built per subrouter, which dropped the namespace and caused the mutation-audit gate to skip these calls. Now we use oRPC's native client for the full router, preserving path, authentication context, dry-run guard, cancellation, validation, and error mapping. The old adapter, type casts, and forwarding helpers are removed. This change is limited to AI tool RPC invocation.

Greptile Summary

This PR replaces the per-subrouter oRPC adapter with a native client constructed from the complete application router, preserving namespaced procedure paths for mutation auditing and tracking.

• Keeps lazy router loading and existing authentication-context construction.
• Retains dry-run mutation blocking, validation, cancellation forwarding, and error mapping.
• Adds focused coverage for full paths, service authentication, AbortSignal identity, missing procedures, validation, and mapped errors.
• Removes the now-unused server RPC adapter.

Confidence Score: 5/5

The PR appears safe to merge, with no actionable correctness, security, or repository-rule issues identified.

The native full-router client matches existing two-segment callers and router structure, restores the complete middleware path, and preserves the adapter’s authentication, cancellation, dry-run, validation, and error behavior.
