* fix: add APP_VERSION fallback and HOST bind env var (#952#953)
- Read package.json version when APP_VERSION env var is absent so the
startup banner shows the correct version for source/Proxmox installs
- Add HOST env var to control the HTTP bind address; only applied when
set so Docker deployments are unaffected (bind-all-interfaces default)
- Parse PORT as Number() so malformed values like '10.0.0.72:3001' fall
back to 3001 instead of silently misbehaving
- Document HOST in .env.example, Environment-Variables wiki, and
Install-Proxmox wiki with explicit warnings against using it in Docker
* fix: correct package.json path in APP_VERSION fallback
index.ts sits at server/src/ — one level up reaches server/package.json,
not two (../../ overshot to the repo root where no package.json exists).
