jedarden c817e96802 feat: implement repeated-setting change detection with guided calibration
Detects when user changes same config setting 3+ times within 24 hours.
Shows non-intrusive prompt offering help with guided calibration flow.

Guided calibration features:
- Test for false positives (walk around room)
- Test for missed motion (sit still)
- Suggest optimal value based on diurnal baseline SNR and link health
- Apply suggested value button

Files:
- dashboard/js/proactive.js: Complete implementation with localStorage tracking

Acceptance:
- Help prompt fires after 3+ changes in 24h
- Calibration flow tests both directions
- Suggests value based on system data
- Apply button works

When you want to fire an event no matter how a process exits:
* reaching the end of execution.
* explicitly having `process.exit(code)` called.
* having `process.kill(pid, sig)` called.
* receiving a fatal signal from outside the process
Use `signal-exit`.
```js
var onExit = require('signal-exit')
onExit(function (code, signal) {
console.log('process exited!')
})
```
## API
`var remove = onExit(function (code, signal) {}, options)`
The return value of the function is a function that will remove the
handler.
Note that the function *only* fires for signals if the signal would
cause the process to exit. That is, there are no other listeners, and
it is a fatal signal.
## Options
* `alwaysLast`: Run this handler after any other signal or exit
handlers. This causes `process.emit` to be monkeypatched.
