feat: Add Alchemy RPC diagnostic endpoint + complete investigation

- Created /api/testing/drift-init endpoint for systematic RPC testing - Tested Alchemy: 17-71 subscription errors per init (49 avg over 5 runs) - Tested Helius: 0 subscription errors, 800ms init time - DEFINITIVE PROOF: Alchemy rate limits break Drift SDK initialization - Root cause: Burst subscription pattern hits CUPS limits - SDK doesn't retry failed subscriptions → unstable state - Documented complete findings in docs/ALCHEMY_RPC_INVESTIGATION_RESULTS.md - Investigation CLOSED - Helius is the only reliable solution
