♻️ refactor(trpc): extract src/libs/trpc into packages/trpc package

Move src/server/services and src/server/routers (~875 files) into
apps/server/src/ under the dual-path @/server/* alias; fix four
move-induced path breakages (two relative imports in gateway/, one
dynamic import in src/instrumentation.ts, and hardcoded readFileSync
paths in agentSignal promptBoundaries.test.ts).
