[Social Farms & Gardens-Spring-24] Reload map on refresh

[lin-d-hop]

PLease track time for this bug under 'Social Farms & Gardens-Spring-24' on clockify

Description

When you refresh on LX the UI reloads to a new and unsaved map. As we develop more features around the map as document tools users will increasingly be using saved maps and thus a refresh in this way is annoying. It would be great to refresh and reload the map that the user is currently editing.

From Rohit on Element: I think this would be quite easy to do (about 1-2 hours work), by saving the current map ID in the browser's sessionStorage, which persists over site reloads but then gets wiped when the tab is closed

Acceptance Criteria

• When a user has a saved map open and they press refresh, the map is reloaded and reopened to the last saved state.
• If the user is editing a unsaved map, a new map is reloaded as per the current behaviour

Ready for review. Thanks @rogup, the only difficulty I encountered was forgetting the sessionStorage variable is saved as a string, when comparing it to mapId 😅.

Tested a few different maps and actions. LGTM :)
