services: add mood, moodtracker, overleaf, personal-sensing; update ollama

Compose and supporting code for four services that had been running or
prototyped without their config tracked here, per the repo convention that
agap_git holds the compose + config while application source lives in each
service's own Gitea repo.

Only placeholder credentials are included: mood/.env.example and
moodtracker/.env.example ship dummy values, and overleaf/variables.env carries
app name and feature flags only. Real values stay in Vaultwarden.
