feat(ui): dock resource actions in top bar, user menu in sidebar

Teleport application/database/service heading actions into a fixed
#resource-action-hud-slot so they no longer overlay page content.
Render the account menu in the sidebar footer (with collapse-aware
layout) instead of the header, and drop the project card hover arrow.
