V3 Hardening & Fixes: Structured Errors, JWT Fallbacks, and Module Stability

- Implemented Structured Error Handling across GET/POST/PATCH helpers to extract rich V3 error metadata.
- Added direct localStorage fallback for JWT detection to resolve race conditions during initial page load.
- Fixed async race condition in Archives leading to 'archive_content_li is undefined' crash.
- Hardened generic object processor to handle non-array API responses gracefully.
- Resolved zero-result bug in Event Search by using raw 'account_id_random' to bypass backend mapping conflicts.
- Isolated bootstrap headers in +layout.ts and removed invalid response headers from request config.
- Enhanced /testing dashboard with live header inspection and V3 hardening audits.
