chore(apps): sweep pin bumps — gitea 1.27.3, vaultwarden 1.37.2, filebrowser 2.63.23, home-assistant 2026.8.3, adguardhome 0.107.79, portainer 2.45.0, pine-whisper 3.6.0

First upstream sweep since v1.8.5: the safe patch/minor pins, mirrored
into our registry first (source.archipelago-foundation.org/lfg2025/*).
Held for their own careful passes: the majors (grafana 11, nextcloud,
uptime-kuma 2, bitcoin-core 29, the DBs) and consensus-sensitive apps
(fedimint, electrumx 2.0). LND 0.21.2 needs an in-house image build —
upstream publishes none.
