Strip hosting Team & Developers pages; point to central account hub

Team and developer-token management now live on account.ladill.com. Remove the
local account.team* and account.developers* routes, the DeveloperController, and
the (empty) hosting Team/Developers pages; repoint the sidebar Team link to
ladill_account_url('/account/team'). The acting-account switcher (account.switch)
stays — it is load-bearing for multi-account access. Hosting developer-access
authz is already centralized via the identity API (shadow-verified + flipped).
