Establish the self-contained tools convention and prove it on a core app:
- discovery now reads containers/<app>/tools/<app>.tools.json (the tools/ subfolder);
tool functions live at containers/<app>/tools/*.sh, auto-sourced by the container
scan (depth 3) — no scripts/app/ entry, no array regen.
- adguard migrated: its 2 Tools-tab actions (reset_password, apply_dns_updater) moved
to containers/adguard/tools/ + tools/adguard.tools.json, and dropped from the
central webui_tools.sh heredoc. adguard_auth.sh stays in scripts/app/ — it's a logic
helper, NOT a tool (the key distinction: only DECLARED tools move).
Central + per-app styles coexist (pihole etc. still central), so the remaining apps
can migrate one at a time with nothing breaking. Verified: heredoc valid sans adguard,
per-app merge re-adds adguard's 2 tools, scripts array dropped the moved fns.
