feat(tags): connect resources to a tag from the tag page

Add a "Connect to resources" modal to the tag show page for small
screens, where the tags canvas is hidden. A new toggleResource action
attaches or detaches the tag on a team resource after an authorization
check, then refreshes the tag's applications and services.

Also improve responsive layouts:
- Wrap section headings, project/environment toolbars and view toggles
  on narrow screens; keep modal headers from shrinking.
- Move the environment settings link to an icon next to the environment
  name and link the project name back to its environments.
- Group project icon, name and description into one "Project details"
  form with an unsaved-changes bar.
- Show dashboard "view all" links for projects and servers only when
  there are more items than the dashboard limit.
