chore(db): migrate Drizzle v1 compatibility

[RSO]

Summary

• Pin Drizzle ORM and Kit to the v1 beta line and make the Postgres Kit config explicit for schema and migration-table handling.
• Convert Postgres and Durable Object SQLite migration artifacts to the v3 folder layout expected by Drizzle v1.
• Preserve existing relational query semantics by routing RQB v1 call sites through db._query and adapting runtime/migrator call shapes.

Verification

• Reviewed generated v3 migration folders and Durable Object migration bundles for the converted artifacts.
• N/A for UI/browser verification; this is a dependency, migration, and compatibility update.

Visual Changes

N/A

Reviewer Notes

• RQB v2 adoption is intentionally out of scope; this PR keeps current query semantics via compatibility APIs.
• Before production rollout, validate the Drizzle migration-table upgrade against a staging/restored production database snapshot and confirm no historical migrations reapply.

CRITICAL: SessionIngestRPC is no longer exported from the worker entry module

cloud-agent-next binds to session-ingest with "entrypoint": "SessionIngestRPC" in services/cloud-agent-next/wrangler.jsonc. Wrangler resolves that entrypoint from src/index.ts, so after this refactor the service binding no longer has a target and the createSessionForCloudAgent / deleteSessionForCloudAgent RPC calls will fail.
