Switch workspace on invitation accepted

[VitorVieiraZ]

• Added workspaceId to InvitationsModel after /v1/workspace/invitations endpoint began including this field with each invitation. After accepting a workspace invitation, app now switches to accepted workspace and navigates to its project list if server version is bigger than 2025.4.1 ( see https://github.com/MerginMaps/server-private/issues/2936 ).
• Added a new method serverVersionIsAtLeast to check whether server version meets or exceeds a required minimum version.
• Changed icon of addIcon method in NotificationModel from WaitingIcon to InfoIcon.

Resolves #3847
