Stabilize Firecrawl startup on PD

- catch Paperless handoff exceptions during assignment intake
- preserve local submission records when archive handoff fails
- redirect HTML uploads back to the form with readable status details
- show archive-pending messaging instead of a raw 500 page

+Firecrawl stability note on PD:
+- The upstream `harness.js --start-docker` launcher fans out into API + queue worker + extract worker + NUQ workers.
+- On PD, the default fan-out has caused first-start flaps (`Port 3002 did not become available within 60000ms`) and steady `WORKER STALLED` / `Can't accept connection due to RAM/CPU load` messages.
+- Keep the PD compose defaults conservative unless the host is re-sized: `NUM_WORKERS_PER_QUEUE=1`, `CRAWL_CONCURRENT_REQUESTS=1`, `MAX_CONCURRENT_JOBS=1`, `BROWSER_POOL_SIZE=1`, `NUQ_WORKER_COUNT=1`, and `HARNESS_STARTUP_TIMEOUT_MS=180000`.
+- After changing those values, force-recreate `firecrawl-api` and confirm `curl -sS http://127.0.0.1:3302/` answers on the first start without an immediate harness timeout.
+

 - Back up `docker-compose.yaml` before live edits under `/home/truenas_admin/doris-backups/`
