feat(web): manage dictionaries and teams from the console

The console could not create dictionary entries, and team pages showed a
static member list with no record of who changed what. Dictionary
management, a knowledge upload form, and a team activity feed are now
available, alongside a download center that links the published desktop
installer feed rather than repository-local paths that no deploy ships.

Red-team e2e coverage was added for the account and team flows touched here.
