Add T0 analyst reports for active IPOs

Request:
- Analyze HK IPO ticker 01392 with the analyst skill.
- Preserve the in-flight 06132 archive/report work already created for the prior request.

Changes:
- Archived official HKEX prospectus PDFs and extracted text for 01392 and 06132.
- Seeded structured T0 facts into the SQLite archive and refreshed CSV snapshots and sync state.
- Rebuilt the v0 analysis dataset and model calibration report.
- Generated Simplified Chinese T0 prospectus-stage analyst reports for 01392 and 06132.
- Adjusted report stage calendars so T2 uses the previous business day before D1 when listing is separated from allocation by a weekend.

Verification:
- Compiled modified Python scripts with in-memory syntax checks.
- Ran SQLite quick_check and foreign_key_check.
- Confirmed DB row counts match CSV snapshots for key tables.
- Verified 01392/06132 source paths are repo-relative, raw files exist, hashes match, and PDF text manifest rows are ok.
- Ran git diff --cached --check.

Next useful context:
- 01392 T1 is due on 2026-06-18; rerun analyst after allotment results are archived.
- 06132 T1 is due on 2026-06-22; rerun analyst after allotment results are archived.
