test: coverage push 95.23% — deep tests for 30+ modules, tracks #353

308 new lines covered this batch (2,605→2,297 missed). Import + smoke
tests replaced with exercising tests for iom, oig, sync, flow, llm,
droplet, cloudflare, postmark, resend, export, project, ingest, plus
CLI --help coverage for all bib/prisma/zot/rec commands.

Remaining gap to 99%: 1,816 lines across cli/, mail/droplet, prisma/vpn,
bib/regulations_gov, prisma/fetch. All require mocked CliRunner or
httpx/pydo/subprocess exercising tests. Work continues — this commit
preserves progress.
