Wire foundation modules into runtime paths

[Dadud]

Summary

This PR starts integrating the architecture foundation modules into live runtime paths:

• validates startup config through the shared config module in �ot.js and webserver.js
• replaces hand-written database table creation in �ot.js with �pplyMigrations
• routes SDRTrunk, TrunkRecorder, and rdio-scanner upload metadata through the ingestion normalizer before calling handleNewAudio
• preserves existing upload response strings and handleNewAudio payload fields
• adds a regression test for rdio-scanner provider normalization

Why

The previous foundation PR added tested building blocks. This PR begins moving real app code onto those blocks without taking on queueing, frontend decomposition, or deeper auth changes yet.

Verification

• npm test
• npm run check:syntax
• npm run check:config

Notes

This is stacked on top of PR #10, which is stacked on PR #9.
