Add Navigation guards to prevent leaving pages during critical actions

[srimanachanta]

Users shouldn't be able to navigate away from pages when:

• They have unsaved changes (either Camera or Network Settings).
• Have a look remake dialog open (Camera or Pipeline Name).
• Actively in the Calibration process.

Confirmation dialog can be opened on the guard request that can clean up the state and store before navigating away from the page.
