Dimensional Flux

feat: polish the network screens and add the showcase link

• Empty states: a tab with no network to work on now shows a compact glass card with the icon of the tab that solves it, the message and a hint, and right under it a button as wide as the card. With no network at all the button is New Network; Choose Network appears once some network exists. A tab in its empty state opens in the standard window size, and the window lays itself out again when the tab gains or loses content. Device Statistics keep showing the device's own figures without a network.
• Members: when both FTB Teams and a scoreboard team (/team) can share a network, one card with a three-cell selector (/team, none, FTB Teams) replaces the two cards; only one kind of team sharing is active at a time.
• Network Statistics: the storage line is written in a deep or bright shade of the network color over a lighter gauge fill, so it stays readable on colored networks.
• The Dimensional Core recipe makes one core instead of four; a GameTest checks it.
• The mod list (Catalogue) links to the Dimensional Flux showcase page.
• The mod icon and logo were updated.
