fix: address review feedback - import ordering and docstring migration

- Move ScheduleParser import before logger assignment (PEP 8 E402)
- Migrate comprehensive docstring from base.py to shared.py
- Preserve original examples (*/6h, */30s) and doctests
- Use explicit re-export syntax to avoid noqa suppressions

 Auto-generated API server for PraisonAI agents.

+Security defaults
+-----------------
+
+Authentication is enabled by default and the server binds to localhost.
+To run unauthenticated (e.g. inside a trusted private network behind an
+authenticating proxy) set ``PRAISONAI_API_AUTH=disabled`` explicitly.
+
+Configuration via environment variables:
+
+* ``PRAISONAI_API_AUTH``   - ``enabled`` (default) or ``disabled``.
+* ``PRAISONAI_API_TOKEN``  - bearer token required when auth is enabled.
+                             If unset, a random token is generated at
+                             startup and printed to stderr.
+* ``PRAISONAI_API_HOST``   - bind host (default ``127.0.0.1``).
