feat(api): seedgo compliance — json_handler, introspection, diagnostics (#69)

* fix(ai_mail): resolve relative mailbox_path bug + archive dead handlers

Fix get_user_by_email() and get_all_users() returning relative mailbox_path
values from registry instead of absolute paths (causing doubled paths in reply).
Added path resolution matching get_current_user() pattern.

Archive 7 unused handler files to apps/.archive/ (gitignored):
- pending_work.py — planned feature, never wired
- lock_utils.py — superseded by inbox_lock.py
- data_ops.py — consumer (error_monitor) was archived
- config_generator.py, users/load.py, registry/validate.py — scaffolded, never used
- trigger/error_handler.py — superseded by trigger branch's event system

Added test_user_paths.py (13 tests) covering absolute path resolution.
