feat: make background polling disablable with on-demand fallback

Browse Source 
- Set POLL_INTERVAL=0, off, false, or disabled to disable background polling
- When disabled, data is fetched on-demand when a user opens the dashboard
- On-demand results cached for 30s so other users benefit from fresh data
- A user with a faster refresh rate keeps the cache warm for everyone
- When polling is enabled, behaviour is unchanged (default 5s)
