Improve install command output ordering and path display

Reorder output so file-write confirmations appear immediately after
secret generation, move "To start Fabro" call-to-action to the end,
collapse duplicate blank line, shorten home-dir paths with ~, and
style the `fabro server start` command with bold cyan.
