LibrePortal/scripts/backup/locations/location_paths.sh
librelad e4872ab511 refactor(paths): single source of truth for a relocatable, split layout (phase 1)
Introduce scripts/source/paths.sh as the canonical path resolver for three
independently-relocatable roots:
  LP_SYSTEM_DIR      manager-owned control plane (configs/logs/install/db/ssl/ssh/migrate)
  LP_CONTAINERS_DIR  container-user-owned live app data
  LP_BACKUPS_DIR     container-user-owned backup repos (own mount-able)

Roots come from the environment when set (install bakes them; CLI/app inherit
from init.sh), else default to /libreportal-*. A transitional compat default
keeps EXISTING installs (legacy single /docker tree, by config marker) on /docker
until a deliberate reinstall, so deploying this never strands a running box.

- init.sh derives the same vars inline (self-contained for the bare /root/init.sh
  reinstall case); paths.sh mirrors it for the standalone task/check processors,
  which now self-locate their scripts dir and source it.
- Replace functional /docker literals with the derived vars across runtime,
  install, backup, crontab, crowdsec/restic, headscale, and reinstall paths;
  clean the inert '== /docker/containers/*' guard fallbacks to the variable form.
- backend: CONTAINERS_DIR now from LP_CONTAINERS_DIR (compose env, filled at
  generation via a new CONTAINERS_DIR_TAG), legacy-safe default for un-recreated
  containers.
- backup default path falls back to the backups root; exclude paths.sh from the
  sourced-file arrays (bootstrap file, sourced explicitly).

The CLI-wrapper heredoc + root helpers still reference /docker; those get baked
in phase 3. No layout/ownership change yet (phase 2).

# kopia.config — kopia adapter's connection state (chmod 0600)

# Everything for one location is co-located here so add/remove operations
