refactor(pdf-compress): replace Ghostscript with qpdf + iLovePDF API
Ghostscript -sDEVICE=pdfwrite fundamentally re-encodes fonts, causing garbled text regardless of parameters. This cannot be fixed. New approach: - Local: qpdf-only lossless structural optimization (5-30% savings, zero corruption risk — fonts and images completely untouched) - Cloud: iLovePDF API integration (auth → start → upload → process → download) with 3 levels (recommended/extreme/low), proper image recompression without font corruption Frontend: 3 modes (cloud recommended, cloud extreme, local lossless). Docker: ILOVEPDF_PUBLIC_KEY env var added. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
