Fix logging directory permission handling

- Add robust writeability testing for logs directory
- Implement fallback hierarchy: logs/ → /tmp/libravatar-logs → user-specific temp
- Handle cases where directory exists but isn't writable
- Prevent Django startup failures due to permission errors

Resolves development instance startup issues with /var/www/dev.libravatar.org/logs/
