journal: typed job seam + Komoot credentials through the manager
Two related fixes from the architecture review:

Typed job seam. Job payloads were `unknown` end-to-end: every handler
opened with `job.data as SomePayload`, every enqueue site passed a bare
string queue name and an unchecked object, and a typo meant a runtime
failure in a background worker. packages/jobs gains defineJob(), which
keeps the payload typed inside the handler and performs the
contravariance cast once inside the package. The journal declares all
14 queues and their payload shapes in app/jobs/payloads.ts; enqueue()/
enqueueOptional() and defineJournalJob() key off that map, so enqueue
sites and handlers cannot drift and queue names are compile-checked.

Komoot credential bypass. The bulk-import route enqueued the raw
credentials JSONB in the pg-boss payload, skipping withFreshCredentials
entirely: credentials sat at rest in the job table, were never
refreshed if stale, and markNeedsRelink never fired. The payload now
carries only the serviceId; the handler resolves fresh credentials
through the ConnectedServiceManager at execution time, and marks the
import batch failed (instead of leaving it pending forever) when
credential resolution itself fails.

// Process-level pg-boss singleton. server.ts initializes the boss + starts
// the worker; feature code (e.g., activities.server.ts) calls `getBoss()`
// to enqueue jobs against the same instance. The singleton's lifecycle
// is bound to the Node process — startWorker calls boss.start(); the
// SIGTERM handler stops it.
//
// The instance lives on globalThis, NOT in a module-local variable. In
// production there are TWO copies of this module in the process:
// server.ts imports the TypeScript source directly (node
// --experimental-strip-types), while route handlers live in the
// bundled build/server/index.js with its own module instance. A
// module-local `_boss` set by server.ts is invisible to the bundle, so
// every request-path enqueue (notifications fan-out, federation
// deliveries, komoot imports) silently failed in production with
// "pg-boss not initialized". Symbol.for() gives both copies the same
// global registry key.
import { logger } from "./logger.server.ts";
import type { JobName, JobPayloads } from "../jobs/payloads.ts";
// Structurally typed (we only need `send`) so we don't have to pull
// pg-boss into the journal app's dep graph just for the typedef.
