Refactor LocalStorage and associated hooks

[somebody1234]

Pull Request Description

• Close https://github.com/enso-org/cloud-v2/issues/1586
  • Refactor localStorage to use functionality returned by a single function, rather than registering keys plugin-style when modules are loaded.
    • This avoids errors when a module tries to read a key when the module defining the key has not yet been imported.

Important Notes

None

Testing Instructions

• Make sure local storage keys are loaded and saved as appropriate:
  • ToS and Privacy Policy modal should not reappear on reload
  • Displayed columns
  • Sidebar open state
  • Local root directory (accessible from gear icon beside "Local" category)
  • Extra local root directories (below the "Local" category in the sidebar - added by "add folder")

@somebody1234 as far as I remember, on a call related to this PR, we decided to compare our implementation with zustand persisters: https://zustand.docs.pmnd.rs/integrations/persisting-store-data and choose an apropriate solution together. Any updates on this?
