feat(backend): add structured logging throughout API

[JohnMartin0301]

Added Python's built-in logging module across all blueprint files to make debugging production issues easier.

Changes made:

• Configured logging in __init__.py with a consistent format and request timing via before_request/after_request hooks
• auth.py — logs register, login, refresh, and logout events
• articles.py — logs create, update, delete, and error cases
• authors.py— logs create, delete, and conflict cases
• tags.py — logs create and delete events

Note: The create_app factory was reading DATABASE_URL, SECRET_KEY, and JWT_SECRET_KEY from the environment before applying test_config, which caused all 21 tests to fail with KeyError even before this PR's changes. Fixed this as part of the work to get tests passing — the fix is outside the scope of this issue but was a blocker for verifying the logging changes.

Test results:

@JohnMartin0301 is attempting to deploy a commit to the devanprigent's projects Team on Vercel.

A member of the Team first needs to authorize it.

This looks great ! The logging integration is clean.

Regarding the note, that was a real issue. Good you fixed it.

I'll merge this
