Subject: [PATCH] Add container timezone management for birdnet-pipy addon

- New init script 02-timezone.sh: reads TZ from addon config, validates
  against /usr/share/zoneinfo, applies to container (/etc/localtime,
  /etc/timezone, s6 container env)
- Change default TZ from Etc/UTC to Europe/Paris
- Increment version to 0.5.6-2
- Update CHANGELOG.md and DOCS.md
