docs: update README for batcave.biz support, delete feature, and FlareSolverr

- Add delete button (SVG X, hover-reveal) and confirmation modal to comic cards
- Add DELETE /api/comics/delete endpoint with path traversal protection
- Fix container downloads: delegate Cloudflare-blocked requests to FlareSolverr
  (headless Chrome sidecar) instead of retrying with Go HTTP client, whose Linux
  TCP fingerprint is flagged by Cloudflare even with network_mode: host
- Add FlareSolverr service to docker-compose; inject FLARESOLVERR_URL env var
- Add diagnostic logging to BatcaveBizMarkup request flow
- Trim URL whitespace before storing in download job
- Guard Archive() against empty filelist; fix runJob error-check ordering
