refactor(admin): split 1089-line admin class into 7 focused files

Addresses excessive line count in Peptide_News_Admin (1089 lines)
by extracting responsibilities into single-purpose classes:

- class-pn-admin-assets.php (88 lines): CSS/JS enqueuing
- class-pn-admin-menu.php (98 lines): Menu & submenu registration
- class-pn-admin-field-renderers.php (325 lines): 25+ field renderers (static)
- class-pn-admin-settings.php (289 lines): Settings registration & sanitization
- class-pn-admin-log-viewer.php (155 lines): Plugin log viewer UI & AJAX
- class-pn-admin-settings-page.php (214 lines): Settings page + manual buttons
- class-pn-admin-dashboard-pages.php (109 lines): Dashboard/articles/cost pages
- class-peptide-news-admin.php (143 lines): Thin orchestrator (delegator)

All files under 300 lines. Original public interface preserved exactly
so no consumer code or tests break. Updated ARCHITECTURE.md.
