Improve pre-mission checks and alerts

[prasm313]

Describe the improvement you would like to see

Mission pre-checks

• Should implement all backend checks (offline, pressure, battery) in one function (all endpoints should use the same function) #1491 Add a common mission pre-check function #1602
• Have a discussion whether the pre-check should be done in frontend or backend
• Should have a backend pre-check for high pressure, not just low pressure (Add a common mission pre-check function #1602 )
• Should not be able to schedule a mission when the robot has connection issues Add offline and isarConnected prechecks #1620
• When a robot is running on Deck1 you should not be able to schedule a mission on Deck2 (Echo missions). #1522
• Should remove possibility to rerun a "Return to home" and "Localization" mission. (today you get a alert banner "Failed to rerun mission") Remove rerun button for localization and return to home missions #1603

Alerts

• UX for user alerts and notifications, see comment
  • Only generate banner alerts for specific alerts. Generate list alerts for all alert.
  • Create alerts page.
  • Create functionality for silencing alerts, removing the "red dot" under the alerts icon when there are no new alerts.
• Store alerts and alert timestamps
• Implement remaining alert types
  • Aborted missions
  • Low battery
  • Low pressure
• Implement alert feature #1560 - In order to improve user clarity
  • Implement alert list feature #1713 - Frontend dropdown alerts menu, no change to alert behaviors.
  • Create a timestamp showing how old the alerts are in the front end and sort list alerts with newest first.
  • Make it so notifications are not overwritten when a new one is generated.
  • Make alerts persistent and do not disappear on page refresh for a defined time. I.e. currently "Request error" alerts disappear on page refresh.
  • Failed missions banner don't pop up or update when missions fail #1724
• Update message in robot-is-blocked banner #1523 - Change text for blocked error banner

How will this change existing functionality?

Will make Flotilla easier to navigate for the users.

How will this improvement affect the current Threat Model?

Edited text to reflect current identified gaps for a well working alerts feature. #1713 provides the implementation of a notifications drop down menu, but does not change alerts behavior. With this alerts are generated twice in order to not remove any current functionality. This is temporary until a discussion on desired notification behavior and what alerts to display when is had.
