The one where we actually get a decent Web UI

This is the first real attempt at making the WebUI much more to a practical liking!

Layout:

• Grid expanded from 3 to 4 columns
• Max width expanded slightly to accommodate 4 columns
• "DHT Statistics" renamed to "Stellar Transport"

Stellar Credits card:

• Added visual longevity progress bar to track bonus
• Shows current bonus percentage and progress toward max (+52% at 52 weeks)

Galaxy Map

• Live peers (in routing table): Green labels, full brightness, larger size
• Cached systems: Desaturated reddish tint, dimmer, smaller size
• You: Blue label, largest size, pulsing ring effect
• Added a "center on Genesis" button to the map
• Reciprocal connections (both nodes have each other): Solid cyan lines
• One-way connections: Dashed orange lines
• Added a legend in the top-left explaining the visuals
• Tooltips showing Name, status (You/Live/Cached), star class description, coordinates, and distance from you
• Hovering a star brightens all connections to/from that system
• Black hole now has accretion disk glow to remain visible against dark background

Other:

• Instead of a full page refresh every 30 seconds, now only the text refreshes, so as to not interrupt map browsing.
• Added Export JSON button for network topology data
• Star colors adjusted for better visual distinction (less astronomically accurate, more readable)
