Screen.Recording.2026-02-11.at.11.45.42.mov

This PR includes various fixes to Employees, Tasks, and the LocationState service.

Changes are listed below:

/users

• Update the admins' Manage Users page to:
  • only show users within their company
  • only show locations within their company
  • correctly assign a location to a user

/tasks

• Fix generic tasks not showing up for employees

Nav Bar

• Remove My Tasks view from managers' and admins' Nav Bar
• Remove Inventory view from employees’ navBar

Miscellaneous

• Update the admins' /settings/locations page to properly add users to a location
• Fix app freezing and not updating for employee dashboard when an invalid API key is assigned
• Minor UI updates

Known Issues:

• LocationState is still not persistent on refresh, the app is persistent across pages, and will show info from that location everywhere, but will go back to the first location when the app is reloaded.
  • Will address this in another PR, but wanted to get these changes banked.
