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.
Move proxy, sentinel, resources, and terminal into the server sidebar
with nested routes and icons; extract navbar status into a shared
status-summary component; add full-width service links and compact
loading support.
Add a shared resource-heading-tabs scroller with overflow chevrons,
wire it into resource/server navbars, keep links menus outside overflow,
and default new git apps to Railpack instead of Nixpacks.
