V1.0: Class 1 fax — real-world 4-page send to external number confirmed

Core features:
- Class 1 T.30 protocol: full send/receive implementation
- HDLC: DLE-stuffing, FCS strip, USR5637 bit-reversal handling
- T.4 MH encoder/decoder (1728px A4 standard)
- Document pipeline: PDF (Ghostscript), PNG, TIFF input
- Width clamping: US Letter 1734px → 1728px fax standard
- Cover page: CJK rasterization (TW/CN/JP/EN), TIFF + HTML output
- OCR verification: Tesseract 5 with eng+chi_tra, CJK space-tolerant
- API server (axum): health, send, jobs, cover, retry, cancel
- Background worker: auto-poll queue, speed fallback, retry policy
- Modem detection, pool management

Real-world test results (2026-07-23):
- V90 → 25153038: 4 pages, V.17 12000 bps, 2:33 ✅
- USR5637 → 25153038: 4 pages, V.17 12000 bps, 2:26 ✅
- Both faxes confirmed received on remote machine

Tested: loopback (100% pixel match), multi-page, all input formats,
cover pages, OCR verify, API endpoints, worker processing.
13 unit tests pass, 0 new clippy warnings.

Add cover page support with Chinese font rendering

Features:
- Cover page generation using Python/Pillow with Apple PingFang font
- CLI commands: cover-create, job-cover for cover page management
- API endpoints: PUT /api/fax/jobs/{id}/cover for cover modification
- Send fax with cover page: --to, --from, --subject, --note options
- Multi-page TIFF parsing for PDF conversion (fix: all pages now sent)
- Preview HTML generation with pan/zoom support
- OCR verification for cover page content
- Class 2 receive support for incoming faxes

Fixes:
- Modem initialization before Class 2 mode entry
- Dial timeout handling with retry logic
- Multi-page fax transmission between pages
- Chinese character rendering in cover pages (Apple native fonts)
