fix(web): stop telemetry poll from overwriting config edits

[stritti]

Problem

The 2-second telemetry poll (loadTelemetry()) unconditionally wrote the Pool/Time tab form fields from /api/status — even while the user was authenticated and editing. Any in-progress edit was reset to the server value within 2 seconds, and if the poll fired between the edit and the Save click, the save even persisted the reverted original value.

Fix

Only populate these fields when unauthenticated (read-only display). Once logged in, /api/config (via loadConfig()) is the authoritative source and the poll no longer touches the form fields. Invalid input is still rejected by the existing frontend validation (validateSettings()).

Verification

• node --check data/web/app.js passes
• Deployed via OTA to NORVI (192.168.178.24); served app.js confirmed to contain the guard
