fix: remove host FDE requirement, fix remaining audit partials

Host FDE is no longer required — only guest (ISO) FDE matters per owner
direction. The build host's security posture is the owner's responsibility.
The Docker container already isolates the build process.

Changes:
- run.sh: Removed check_host_fde() function and its call in iso build path
- run.sh: Fixed SB key chmod in inline SECUREBOOT_HOOK (C-04 complete)
- run.sh: Fixed cache manifest format — no longer capped at 20 files (H-09)
- docs/PRD.md: Removed FR-011 Host FDE, renumbered FR-011 = Secure Boot/UKI
- docs/COMPLIANCE.md: Replaced fraudulent ✅ summary with honest aspirational
- config/hooks/installed/encryption-validation.sh: lsblk discovery (H-06)
- src/security-hardening.sh: Synced WiFi blacklist with live hook (M-12)
- tests/: Updated 3 test files for guest encryption instead of host FDE
- AGENTS.md, README.md, audit docs: Removed host FDE references
- STATUS.md: Updated for current state
- JOURNAL.md: Added ADR-017 (host FDE not required)

782 tests pass, 0 fail, 0 shellcheck warnings.
